So, I thought I might delve into other issues with this watch. Today, I took the phone off my wrist for an hour and a half then put it back on. During that period it magically carried on recording blood pressure and blood pressure. Although the activity was correctly recorded as zero, the heart rate was 104 when the phone was on my desk. This is clearly nuts, so along with the fake looking blood glucose results, I have serious concerns over the functioning of this watch. That, along with the lack of recognised manufacturer means that I would not recommend buying this watch. Shame I wasted good money on one.
Yes, I have an E400 and I see my trends. It always makes sense, buy I'm sure the actual numbers are not accurate. It's just sharp enough to show you if something you just ate is creating a response, and is a little dull to determine how high it really is. For 30 bucks, it helps me to figure out me.
I have the E420 for about 6 weeks now The step count I just had a 2km walk and it showed 687 steps , as as it does not even come close to my 2 other devices which are within 100 steps for the whole day Sleep tracking, what a waste of time, once again it is not even close to my 2 other devices Blood pressure, I test it 3 times in a row and it comes up with 3 readings vastly different from each other When comparing it to a blood pressure monitor it is not even close The readings seem to fall within a constant range each day and also comparing days to each other Blood glucose my daily figures are almost identical to yours Fasting days have the same numbers eating days When I have breakfast it is at 5am and the glucose peaks is at about 10am The numbers do not even remotely compare to my Libre monitor The only good side is that I paid less for mine than you did Yes it was worth the cost to find out this
If you wear the E420 (which I have) for a few days, you will see that the blood glucose chart is identical each day. This is very easy to see if you flick between days and observe the blood glucose chart. This indicates to me that this measurement just doesn't work and provides misleading data to the wearer. The other physiological measurements seem more reliable, but frankly who knows? It's hard to trust a device where at least one set of measurement is clearly inaccurate and possibly faked. With this type of purchase, there is no-one you can complain to so beware of generic smart watches with no recognised manufacturer.
Well, the one I take with me when I want this kind of data is the E500 because the ECG measurement produces an actual chart on the watch screen, unlike the other "E" series watches. So I haven't used the E400 line very much beyond producing these reviews. I don't want to state which is 'best' without actual knowledge to form a baseline opinion. I will mention that the chest strap option is a good idea if you want to record ECG charts in the tethering app. Otherwise, you need to activate a recording from within the app, as shown in the videos.
I doubt either of these watches would match up to the readings of actual certified medical devices. If you are buying either thinking that you are getting accurate readings for what it supposedly meters I would take it with a ton of salt.
These are NEVER meant to replace certified medical devices and shouldn't be viewed as such. They are limited "toys" to be used with caution and validated personally with true calibrated devices. Thanks for pointing that out.
Don't buy this. Purchased 2 less than 2 months. Both quit working. One can't power on, the second now has issues with not detecting ECG reading with finger on senor on device. Don't buy this , out of $189 for this. Taught me a lesson, should have done my due diligence with researching this.
I wear the e400 AND a Libre Freestyle CGM. The glucose monitor works BUT the numbers are not accurate. I am not diabetic but am on a Ketogenic diet with extended fasting. The pattern of glucose rising and falling of the E400 v the CGM is similar. You won’t know what your sugar is but you will know if it is rising falling in response to diet exercise stress etc. One caveat. If I have something artificially sweetened or with stevia… the CGM stays flat but the e400 rises. It knows I had something sweet even though it wasn’t sugar. Also re glucose rise without breakfast. This is normal. Called Dawn Effect. Your body releases glucose to wake you up.
It costs about $1000 a year to wear a CGM. For $50 or so I can wear this and know how I respond to different foods. Not good for a diabetic but for a person trying to keep glucose flat it works.
@@hammerjoe2008 I am not getting that at all. I go days without eating and it goes low and flat. I normally eat once a day and that is the only response. Sometimes that stays flat as well as usually I only eat steak butter bacon and eggs. No plants.
@@texasgunfyter on the 600 and now 420 that I own the graph line is exactly the same from the previous day and the day before and so on. Now if I look at the numbers that were read by the device at the same time every day, they are slightly different but it results in the same graph line. Its reading something, Im just not sure what because I dont know if blood glucose has the same pattern day after day. I think the only way to test that is for someone to do use a real glucose reader at regular intervals and compare the results after a few days.
@@texasgunfyter Are you using the E400? I also eat once a day at night, and it always does a perfect breakfast spike (not just a slight morning bump as expected) ~1 hour after waking up, and another one around lunchtime when I still haven't eaten anything. Then it does another spike around dinner time, and then slightly after that when I eat a meal with carbs the curve starts coming *down*. Totally bogus. Exact same behavior while doing a 72 hour fast, three spikes per day.
Hi there I prick myself and compare the values the E400 is way off, eg., It shows 4.56 on the watch, and when I price my finger , it states 9.87
Would be nice to know in your reviews if they are LCD or OLED

Dear Mr Ticks,
Please review another ECG smart with built in tws earbuds known as Y7.
I hope you review it soon.
Regards.
Moses.
I assume it's an Arm processor design but which one? I couldn't find any info about it.
I have the E420 for about 6 weeks now
The step count I just had a 2km walk and it showed 687 steps , as as it does not even come close to my 2 other devices which are within 100 steps for the whole day
Sleep tracking, what a waste of time, once again it is not even close to my 2 other devices
Blood pressure, I test it 3 times in a row and it comes up with 3 readings vastly different from each other
When comparing it to a blood pressure monitor it is not even close
The readings seem to fall within a constant range each day and also comparing days to each other
Blood glucose my daily figures are almost identical to yours
Fasting days have the same numbers eating days
When I have breakfast it is at 5am and the glucose peaks is at about 10am
The numbers do not even remotely compare to my Libre monitor
The only good side is that I paid less for mine than you did
Yes it was worth the cost to find out this
Are you testing the Rogbid Model X ? I am interested in this watch..

OK, I meant "blood pressure and blood glucose"
Hi any new BIG smartwatch like the Kospet prime 2?
No, nothing new in the large format. I've reviewed an Apple Ultra clone looking thing in Android though: th-cam.com/video/xUwtQA7prPc/w-d-xo.html
Which would be better between this one and e400?
Well, this is the updated version, but I haven't tested the two versions together to see which is better regarding accuracy, battery life, etc.
You just did in this video? However, which one would you recommend between the 2?😊

Even the best smart watches can never replace medical devices it's just for reference

They both say "Frequency 512hz"
Good

@@texasgunfyter what gets me is that the chart curve is the same day after day, which slight changes in the numbers. Is this normal?
