I got this watch for two reasons. I already had a garmin vivosmart 4, which does super-well at SPO2 monitoring in your sleep (mail reason I got it) and remarkably well at activity tracking etc. It also had a very good android app interface for quickly viewing graphs of its running observations and more. Its flaws were a watch band that is too short and not adjustable, charge that only lasts for 4-5 days tops, and it ONLY does heart rate and SPO2 for health monitoring.So, I got the AMAZTIM, in order to get a much longer runtime per charge and its blood pressure monitoring as WELL as SPO2 and heart rate. It is also a much — much! — bigger watch than the vivosmart so I thought its interface might be a bit better and access to more advanced smartwatch features better as well.I was mightily disappointed. The ONLY part of its hype this watch lives up to is its run time per charge, which is easily more than a week, almost two weeks. What doesn’t is: a) Watch faces that look like they were designed and intended for teen-age adolescents who like cartoon animals. Seriously? Not one, single, watch face that actually uses the vast real estate of this large watch for something other than cartoons, fancy backgrounds, science-fiction spreads? Nothing that (for example) displays time/date/heart rate/SPO2/steps/BP? There’s plenty of room for all of this…but instead we get cartoon beaches with only the time. b) The Blood Pressure it measures is completely useless. I mean, off by 20-30 points useless, when compared to BP taken by actual cuffs by actual nurses or physicians. 20-30 points low useless — I’m healthy as a horse according to the watch, 106/66. Only not — PROBABLY more like 126/80 — if not higher (which is the problem). c) Heart rate is not too accurate either. I tend to run slow, but it thinks that I’m up at 82 after sitting completely still for over an hour. d) SPO2 almost always reads 99%. I do have an oximeter to compare to, and it reads more like 96-96% where the Garmin reads 94-95%. I trust the Garmin to be consistently low, because if I e.g. hold my breath to drop SPO2, it remains a couple of percent under. I’m not sure I trust the always 99% reading. Again, great if true, but almost too good.But the worst of all is the Da Fit app. It isn’t even in the same UNIVERSE as the Garmin Connect app. Garmin plots data on an actual graph with time as an actual axis. You can see how your heart rate changes over the entire day, as it constantly samples it. It doesn’t CONSTANTLY sample SPO2 — I wish — but it DOES sample it for a selected four hour window while you sleep, making it actually amazingly useful for determining whether or not you have Sleep Apnea when your wife (the physican) thinks EVERYBODY my age has it — but the Garmin says that I do not. Just sayin’, worth it right there. Cheaper and easier and I’ll bet just as effective as a sleep study, and it runs EVERY NIGHT (one reason the Garmin runs out of charge in five days).The AMAZFIT only samples SPO2 when you, by hand, tell it two — scroll four screens, press a button, wait. It doesn’t automatically sample at night or regularly in some window. It only samples heart rate when you tell it to — well, it actually does sample it all of the time but doesn’t send the data back to the app and display it as a function of TIME. BP is shown only “for the last seven times”, but it doesn’t actually LABEL them with the TIME or DATE you took them. Ditto SPO2 — last seven times you hand measured it, without any sort of timestamp, in a BAR CHART not even a graph.Look, almost anybody’s smart watch will track steps, stairs, hikes, etc — fitness training is easy if rarely completely accurate as they rely on things like accelerometer reading a lot more than they rely on sampling your GPS coordinates. The key health metrics they can currently reach are heart rate (a very few more than just “rate”!), SPO2 (enormously useful if it will run overnight), and blood pressure. Except that so far, BP just doesn’t seem to work, and EEG-quality heart results are still only on very expensive watches, and NONE of these are worth much if you can’t SEE HOW THEY VERY WITH STRESS AND TIME ON A REAL GRAPH.I suppose it is back to the drawing board. It’s very difficult to get a clear and unbiased review of what is out there. I’m tempted by an EEG-capable watch, but that is super limited right now. I’d love accurate — note accurate, within say 5 torr — BP, SPO2 (within 2%, consistently one war or the other around oximeter readings), heart rate — all displayed in real graphs with time axes of a reasonably small granularity — once a minute, say, or once every fifteen seconds depending on what one is looking at. WITH week plus runtime per charge. And sure, with activity/sports stuff too, but that’s a dime a dozen and easy.

I purchased a AMAZTIM 5ATM for my husband primarily to help him keep track of his blood pressure and after researching several smartwatches I decided to go with the AMAZTIM 5ATM.The trouble is I am whatever the opposite of a tech person is and my husband is about as techie as you can be. While he very much appreciated the thought, he immediately knew that neither this smartwatch, nor any other smartwatch, was at all accurate when it came to blood pressure. But he strapped it on and like any other tech person started through all of the options and functions.Naturally, it told the time so we can skip that. What I got from him was the heart rate and O2 were very much in line with a store-bought pulse-oximeter and therefore, as far as he was concerned, reliable and useful.There were a few things that bothered him but I am much more of a positive person so let’s start with the good points. I already mention pulse rate and O2. That seems first rate. Battery life is excellent. Three days and it’s still at 80%. The charger cable, while not the usual mini-USB, connects magnetically. I’m guessing that’s to avoid a slot that water can get into. It’s a nice feature. The watch paired with his iPhone very easily.On the downs-side blood pressure reading were very off but he knew that even if I didn’t and I don’t count it against the product.My husband gets text messages and other app notifications frequently and since he keeps his phone on silent mode and in his pocket, he sometimes misses them. Getting those notifications from the watch sounded like a good deal and he set everything up on the watch and companion phone app, DA Fit, I think it is. He got very frustrated because hardly any notifications from any app came through to the watch. Not zero notifications which would mean it didn’t work at all, but some, which for a very impatient person like himself frustrated him more since he tried to figure it out. He did not figure it out.The weather function, while he didn’t really care about, said it wasn’t paired, which he didn’t know what that meant (the teeny instruction booklet wasn’t helpful), but it did work… once. Again, Mr Frustration cared more about why it worked once than not at all.My husband is an avid cyclist (he’s on his bike more than he’s home sometimes). The Sport Mode, which was supposed to be a long press on the second button, never worked at all.Three categories that really didn’t work is problematic.I did contact the seller and got a prompt next day reply from, I’m assuming, a different time zone. They offered to remediate the issue but unbeknownst to me he sent it back – sigh. I would have given them a chance. Men, right?Bottom line: don’t get any smartwatch for blood pressure and this product in particular has definite shortcomings. The watch itself gets 3 stars but I added a star for the seller who tried to make it right even if my husband didn’t wait.

Review Update.I have finished reviewing the watch and its features. Solid construction, good battery life, and features perform as advertised. Good investment. Customer service is responsive to any issues.Initial ReviewI am still evaluating the watch and its features. I assumed that this was an Amaztim watch but discovered it is a Kospet Tank M2 watch.

The biometrics are fairly accurate. The pulse measure seems to work best with the watch rotated over the arteries under of the wrist.Blood pressure and the rest of the readings seem to work perfectly fine with the watch on the top of the wrist. I have checked blood pressure against my doctors office and have been within several numbers of there readings. The blood oxygen is within a percent of the doctors office. The physical activity tracking works very well.The only negative possibly about the watch is you can’t send texts or make telephone calls through it as you can with some much more expensive similar products. Now to fix a problem I have ran into probably four times since I’ve owned the watch this is screen, freeze wear the watch face will not respond to your finger swipes. This can be fixed by repeatedly, pushing the power and then the back buttons repeatedly in fast succession for probably 150 reps. Eventually, the screen will turn off and restart and the watch will work properly at this point. It has been a good watch. I would recommend it, and I would buy another.

The Watch band is a real pain to put on.Took several minutes to attach to watch.And 3 different people trying.Watch itself works fine and easy to navigate.

This watch has an awesome bluetooth as far as listening to music and talking on the phone plus its pretty loud too for such a tiny speaker.

Great watch and great price for all you pay;also great quality, but had to return it because I have a very small wrist and this watch was too big for me ! Wish I could have kept it for you get alot of bang for your buck !!! Amazon was very understanding and I hadn’t put it on or wore it so they took it back and gave me my total refund ! It was hard to know how big a watch it was until I opened the box and saw it ;and knew instantly it was too big for my small wrist !
