TRY THIS BEFORE OPENING THE MOUSE. For those also having problems with the left button (erratic drag and drop, random double clicks), first try blowing compressed air under the mouse button (avoid air from your mouth). I saw this solution on a Reddit threat and this solved the problem for me and for many people in the thread. Sometimes it is just some dirt on the contacts. Nice video though. Very thorough 👍
I just sprayed some contact cleaner inside the button's hole, pressed on it about 20 times, and dried with compressed air. Worked like new. WIll need to order those switches so I'll be ready next time. We have quite a few users using this model at the office.
Awesome! I've just used your video to give me some assurance while changing my mouse's left button. Now, after changing the left button as you show, it's not having failed clicks and intermittent drags. Thank you very much!
Thank you for such a clear and detailed walkthrough! I've had a stack of these mice building up, since the clicker keeps breaking on each one after about a year. I don't have any experience with soldering, so I figured I better try doing two of them to see if one might work. I burned them both to high heaven trying to get the old switches out, and I killed one of them, but the other one works great now! I never would have tried it without your guide here!
I just installed the new switches. Fairly easy to do and the mouse works like new. The original switch is rated for only 50K clicks (very low in my opinion) The Omron D2F-01F is rated for 100K clicks (still not great), hopefully is lasts longer but still repairable. I really love this mouse.
Thanks just followed your video and replaced both left and right switches while I was at it. Worked like a charm. No more double click problem and not holding the click
Thank you very much for this video. I had two MX Vertical mice with the left button not working reliably with click-n-drag. My first attempted fix failed. I had trouble getting the old solder off after removing the faulty switch, likely because I did not have any solder wick and I probably overheated that tiny board. Maybe I'll try selling that one on eBay for parts. I bought a slightly used one off eBay for just under $50 to replace that one. After buying some solder wick and paying more attention to how you did the soldering, my second attempted fix worked. The MX Vertical is my most favorite mouse. For $100 I wish Logitech would use better switches--I'd gladly pay a few bucks extra, rather than do this repair again... so many tiny screws.
cool, good explanation. I did all steps but unfortunately I messed it up with the soldering portion... I burnt the contacts while removing the solder! For inexperienced people like me maybe it's good to make some trials on the side before trying to de-solder. Had fun anyways! :)
I have the same issue on both buttons, also I have a friend that has the same mouse and have problems with his left button, to me, it seems that is a problem that is persistent with all of those mice.
Thanks for clarifying the left click drag issue. I had assumed it was a bad wireless connection. The problem I'm encountering though is after I disassembled to fix a scrollwheel clog, the Left Button is not clicking both Middle and Left. It's definitely physical, but for some reason every time I reassemble, I can't get the left button to sit right. I can click the left switch itself, but for some reason the shell won't avoid the middle wheel platform. =(
I've got 4 of those mice and love them, very ergonomical ! But after 2 years the left button starts misbehaving. My second mouse is now up for exchange or repair. Think I will blow some air first and only if that is not solving the problem change for a microswitch that can stand 5 times as many clicks (50M). Thank you for a nice video!
As my second vertical mouse is developing a faling left button micro switch I wonder if I should get a new one or repair as seen here. Thanks for the video!
how could i find a rubber for this mouse? mine is totally melted because my country is too hot, also long time using it... its working perfectly but really needs a new rubber, i dont want to buy a new mouse....
Do you know if the Kailh GM 4.0/8.0 switches also work on this mouse? I'm thinking about using those instead since I read a lot of good things about the reliability of those switches.
Thanks for the video. Got mine working again. Left button is a bit stiff, so I think I put it together slightly wrong lol. But it works. Probably gonna buy a different mouse altogether if it happens again
Now we just need replacement shells. I may just strip the ugly deteriorating rubber coating off the plastic while I have it apart during this switch procedure and repaint the shell.
Hey Ruthsarian! I have the same mouse but a different problem... and wanted to get your advice on this! My bluetooth turns on and off occasionally and works for sometime and repeats it... would you have any tips on fixing this? It seems like a physical connection issue with a wire or something within the mouse because it's turns on after I disassemble it, but keeps coming up. Thank you!
the antenna is part of the PCB and probably not part of the problem. but if it works when you plug it in, then it might be related to the battery. either the battery itself is going or perhaps the battery connector is loose and needs to be pushed back in. i'd check the battery connection first. then leave it to charge overnight. if the problem still occurs, it might be time to replace the battery. iFixIt has a good page covering how to do that: www.ifixit.com/Guide/Logitech+MX+Vertical+Battery+Replacement/145407
Merci pour cette vidéo. Je viens juste de terminer le changement du contact de clic gauche et tout fonctionne de nouveau à merveille. Je n'ai pas trouvé le switchs sur amazon france mais sur amazon allemagne et ils les vendent par 10. Bravo !👍👍👍
Tks for the video, it helped a lot. I managed to change the switch, tested and it worked as it should but after 30 minutes of using, the button has completely stopped working. Waited few hours it was working OK again and with 20 minutes of using same problem. I think I might be facing some bad connection or smth like that. Any guess?
that's odd behavior. it could be a bad switch. double-check the solder joints in case one is loose; make sure there aren't any accidental shorts between solder joints as well.
@@Ruthsarian After many tests I've found. Besides it didn't seem a short by solder, smth was short sometimes with the third contact. I just cut the 3rd wire from the board and now it's working fine. (I think somehow the board track should have gone bad)
Thanks for the video. It was difficult because I'm not used to soldering, but now it works well. What did I learn? 1. I need a good soldering iron 2. I need a better "third hand". 3. I need/want a magnetic mat. 4. I need to stop buying Logitech products. This thing was absolutely overpriced. A $100 mouse that breaks after a year is not acceptable. By the way, I didn't completely remove the sliders. Instead, I used a scalpel to make holes in the plastic strips to get to the screws.
The generic term is 'spudger'. They come in all sorts of shapes and sizes. Those triangle ones came in part of a larger kit. You can find spudger kits on Amazon and elsewhere (www.amazon.com/dp/B0762BVXDY/). The triangle ones might sometimes be referred to as guitar picks. If you want just those, here's an amazon listing for a pack of 50 of them: www.amazon.com/dp/B075R3BHKR/
Great video, thanks for sharing! I have the similar issue with my left click. I'll order the same switch. I wonder have you tried anything to clean the mouse surface? I see that you have the same dirt marks as mine :)
There's some sort of rubbery coating on the mouse shell that wears away. The wear will make it look dirty. I've used some isopropyl alcohol to clean the shell and that seems to help, but it's not as much dirt as it is just worn-off rubber and bare plastic.
That I'm not sure about. I haven't found any resources on fixing the scroll wheel. If it's the scroll wheel button, that's the blue button in the middle of this image: guide-images.cdn.ifixit.com/igi/wXDEZiZIdaAQVgJx.huge. That looks like it has the footprint for a standard tactile switch. You'd probably need to remove it and take some measurements to make sure you had a correct replacement, but surface mount tactile switches are pretty easy to find and pretty cheap as well. If it's the scrolling that's the problem, I'm not sure what to do. It looks like it uses an IR LED on one side and 2 IR receivers on the other side of the scroll wheel and it's detecting the IR light passing through holes in the wheel. You could try removing the wheel and cleaning it. If the IR LED or receivers are broken, I'm not sure where you'd be able to find a replacement.
I had one mouse not this model and the button wouldn't work. I sprayed contact cleaner on the switch and pressed the switch several times.. And for the next 24 hours it felt weird and didn't work right.. I think fluid got in the switch. After 24 hours it started working like new, when the fluid dried.. Still works perfectly to this day!
Tip: Use **single** pole switches only! I replaced the left button with a cheap-o 3 contact switch (one pin is Normally Open, one Normally Closed, one Common), the mouse started clicking with a phantom button (Number 9 in `xev`) whenever I pressed left button, or the forward navigation button. I tried desoldering the whole button board (3 pin black wire), yet the behavior was still the same. Replacing the faulty Omron back resolved the issue. Must be intentional failure mode, as all cheap mice use these 2 pole switches. Never failed me so far. Now, I'm waiting for "original" (=still fake) Omron to arrive...
how works the new switch after some time? I'll have to change mine also and I'd like to know if Omron D2F-01F works fine or maybe is there any better option
Tried the soldering, destroyed the left mouse connection. Searched for a replacement board and found one with hot-swappable, no weld micro switches for $11 on aliexpress. Looking forward to getting them installed. Like if you want a video of that install process.
So annoyed with Logitech mice developing this issue so often, like pretty much every Logitech mouse i have got this issue, sometimes after 3 years or sometimes after just a few weeks.
I can't go back to 'standard' mouse. There really needs to be a high end option; preferably with lightweight metals. I can speak too owning a logi mx vertical long-term. Plastic junk as far as longevity is concerned. I have smaller hands and use my logi mx vertical for everything including competitive gaming with a clawing grip. It'll work great for about a year, then the exterior plastic, switches, and mouse wheel deteriorate to a point of non-function.
Wow this looks like an absolute bitch to fix, fuck logitech and their planned obsolescence bullshit, both of my buttons have now failed after barely a year each as my primary mouse button. Kudos to you for the video and to anyone who manages to successfully follow it, especially the soldering part.
Great video, thx for the upload! I managed to disassemble and reassemble mine several times as I was absolutely sure that I would be able to clean some dirty connections of the clicking metallic part inside the D2FC-xxxxxx clicker component of the mouse to avoid soldering as I really feel like a might screw up more due to lack of experience/ good quality tools. Alternatively and in combination with another great video of the fix to the specific part I was able to sort out the problem I had with losing dragging capabilities with left mouse button clicked that I was suffering from the past 9 months. Also save around a 100$ or even the 10$ for the clicking component... :P if anybody encounters a similar issue I would advise to watch th-cam.com/video/2sh7KwUudtI/w-d-xo.html . you could follow on precise disassembly and reassembly of the switch thingy.. I cleaned my metallic clicking part with some spirit alcohol before reassembly and viola! works like a new mouse.
All these Logitech mice and keyboards cost a fortune, but still they use cheap materials. In the case of keyboards, they don’t even provide spare keys. What a shame for the brand
it's definitely not a great look. at work i use a wired vertical mouse i bought for maybe $20 off Amazon BEFORE I bought the MX for myself. It has never had problems. i bought the MX for personal use because i liked the vertical mouse, but I didn't want it wired. i went with logitech because they're "the brand". and considering how much it costs, it should never have had problems with its buttons. and yet...
This is not an easy replacement. The desoldering and soldering of the switch is especially difficult as the existing solder did not want to melt. Also the switch prongs extend out and push the switch face out beyond the face. Clipping off these helped level the switch but after two disassemblies and reassemblies the left button is not providing a sharp click. Errors or misclicks are still present.
TRY THIS BEFORE OPENING THE MOUSE. For those also having problems with the left button (erratic drag and drop, random double clicks), first try blowing compressed air under the mouse button (avoid air from your mouth). I saw this solution on a Reddit threat and this solved the problem for me and for many people in the thread. Sometimes it is just some dirt on the contacts.
Nice video though. Very thorough 👍
it works!
@@frankinshtein Where did you spray the compressed air into the mouse?
@@arbcat69 I lifted the front of the mouse button (where there's already a gap) a bit and sprayed in there. Seems to be working much better now.
I confirm, sending compressed air solved the issue.
blowing compressed air and then spraying a bit of contact cleaner fixed the issue for me
Thanks for this video! Mine is playing up too... and after watching your video and seeing how easy it is... I'm buying a new one 😀
Yes! Same here. Haha
Same here 😂😅
I just sprayed some contact cleaner inside the button's hole, pressed on it about 20 times, and dried with compressed air. Worked like new. WIll need to order those switches so I'll be ready next time. We have quite a few users using this model at the office.

also worked for me
Hey wondering how the mouse is working now? Did you end up needing to change out the switch or has this solution continued to work?

Thanks! You have a great voice-over manner
My mouse is exactly like this one, but there are no screws when I removed the sliding part. Why?
cool, good explanation. I did all steps but unfortunately I messed it up with the soldering portion... I burnt the contacts while removing the solder! For inexperienced people like me maybe it's good to make some trials on the side before trying to de-solder. Had fun anyways! :)
