I picked up the Vevor 4-channel version of this scope for dirt cheap (basically has the Owon SDS1104 control panel which is a little different from the Hanmatek, but the same scope otherwise) - happened to stumble across a heavy Amazon discount offer and coupon on top of it. 78 bucks. Couldn't pass it up for that price, and glad I didn't. The offer was gone the next day and the price was right back up to $199.
No don’t measure mains voltage with any bench scope reference to earth ground. You will blow the input stage. To safely do so you need active differential probe, or handheld scope that not plug into mains is the easy way. Some people remove ground off cord or use isolation transformer but generally not good practice and a hazard in itself. One other option which is to use to do back in the day before getting a HV differential probe as was expensive. If your voltage is 240v UK is to use two probes and remove the ground alligator clip and go to add mode so you can add channel 1 and 2 and invert channel 2 and set both channel to equal deflection factor you measure the different basically substracting both channels and then you can measure the two points without the ground reference. I have to do a video on this. In the US where you are dealing with 120v single phase you just remove ground alligator clip and use a probe in 10x and you can measure AC with a single probe. Make sure you remove the ground alligator clip, or you get a burned probe and impressive arc blast from front end of scope.
it made by Owon just rebadged, they are pretty decent, I have their portable scopes and match advertised specs at 100 MHz. Most Chinese DSO’s don’t as over sample or just lie on specs.
Great evaluation of the specs! Thank You for the information and posting.
They might have put the mains socket on the side so that it can be pushed up against the wall to stop it moving when you push the buttons.
thanks you so much !

Hallo, ich habe mein Gerät gestern bekommen.
Wie kann ich die Helligkeit vom Display einstellen?
Unter Utility/ Display geht es nicht..
Thank you...👍
Some days ago I bought one Labloot, is the same scope.
I pay Us$170 for it.
For the price is a very good option.
Hi, the measurements on Amazon of the product seem larger (in terms of size), could you tell me the measurements of your product to confirm?
Is this a Cat 1 or Cat II scope ie can you measure mains voltages safely?

First chinese DSO I am seeing that the tested BW matches the specs.

"Made by Owon", are you sure about that?
Next time remove the protective tape from the screen also.
