AMATAGE Smart Watch for Android Phones iPhone for Men Women, Fitness Tracker Watch with Heart Rate Monitor , Waterproof Activity Tracker with Sleep Monitor(Black)

I've only had 1 other slimmer model smart watch and thought this might be too big/uncomfortable. I could not believe the price point with the features it had of accessing messages, see if you have a phone call, play music, and do all the tracking. I was especially interested in the sleep tracker. I think the other smart watch that I had did better in that department as far as it also indicated the times I was awake (this program does not) but this one shows you how many hours and the hours or minutes at the levels of deep sleep, REM and light. The time is not accurate, adds at least an hour of sleep that I know I am not getting. It counts the times you are laying still trying to fall asleep (as sleep). It also shows the fastest and slowest heart rate during sleep registration (my other did not do that). I also am not able to program the length of my stride as the shortest it will measure 1 step is 12 inches but I am short and a step for me is not 12 inches. I do not know about other activities as I really do not track exercise. I am impressed that it can assess the blood pressure, the heart rate (continuously) and the pulse oximetry. Again, I am not so sure how accurate it is. My pulse O2 is usually 98-99% but sometimes (3 or 4 consecutive days) it read at 96%. I have a cardiac pacemaker that helps manage my low blood pressure and twice when it felt like my blood pressure was going low, it actually read it as just a wee bit high (which is feasible). The band is way to long on my petite wrist (I wear about 5 1/2" to 6" bracelet. The end of the band is always working itself out of the tabs that help to secure it. I have it secured in the second to the last slot for the clasp--it completely wraps around the wrist with the overhang/excess. But the watch is lightweight and comfortable even in sleep (was skeptical that it would be as I sleep on my side/stomach). The battery still has about 40% and I have worn it for a week now. Another feature that I was surprised with is the flashlight feature. The watch claims to 'turn on' by merely shaking the wrist but I find that feature to be hit or miss, (mostly I need to tap the button). Sometimes I tap on the screen and the wrong feature will turn on rather than the one I was trying to touch (and I have petite fingers). I never have my cell phone on so I cannot attest to how that feature operates but I've no reason to think that it would not given all the other features that seem to work. I have an LG android smart phone and the download of the watch program was simple (and I am technically challenged) but when I tried to download the program on my Samsung tablet, it said it was not compatible. I like the design and that it offers different faces on the clock. I asked about replacement bands and was told there would be some to come but one time the vendor said I could get any band through amazon and the end piece needed to be 30 mm but then he answered again saying the band needed to be 32 mm to fit the watch. I had seen a response to a question on Amazon about this watch that there would be special tools needed to change the band so those things have made me hesitate to order a band. The charge time was maybe 2-2 1/2 hours and the time is accurate (even shows second hand movement) and it registered the time change without my having to manually enter anything. I am impressed with this watch and all its features but again rather than rely that it is absolutely accurate it gives you a sense of what would be your typical measure/level for you in order to compare differences. I hope this helps (as I truly am not tech savvy).

I love that I get to see exactly how many steps I do a day and it reminds me when I need to get up and move a bit more, or simply go for a walk! I also get to see how my sleep goes and since I had been wearing this watch I am getting a better sleep, because it made me realize that I must go to bed earlier :) this is like adding quality of life with one simple step, just wear this smart watch!

I bought this watch after trying several other low price smart watches that did not live up to my expectations, or just died on me as soon as the return window closed.I've had it for two months now and am very pleased with it.I like the size, as it is not too big and is relatively thin, compared to the majority of low cost smart watches. I don't like those huge 50 mm diameter and 16 mm thick watches, so this one was a perfect choice for me. It also comes in several colors and you can change the band as you you like and not limited to a certain brands or styles. Any 20 mm band would fit this watch. I like the silicon band it came with, but may replace it at some point with a black mental band I have from another watch.Battery life is excellent. It takes more than a week at moderate use (not too much measuring and activity) for it to go down to 30% or 40% battery capacity, which is usually when I charge it. Charging at that capacity takes about an hour, which is not bad at all. I haven't tried letting it go dry completely, but assume it would hold charge for about 10-14 days, depending on the usage, as the frequent of BP and heartbeat measure probably uses more energy than less frequent measuring.As for the measurements accuracy, I don't have a way to check the accuracy of the blood oxygen level and blood pressure, but comparing the heartbeat the watch measured Vs. counting my heartbeats, shows that it is pretty much the same. Step counting seems also to be relatively accurate, or at least compatible with my old iPhone's step-counting.Speaking of iPhone, it works perfectly with my old iPhone SE.As for other smart watch features, this watch cannot make calls or accept calls, but it vibrates when a call comes in and shows text messages from various apps, depending on your personal settings in the app. It also allows you to take pictures using your smart phones camera, which could be useful when trying to take selfies.One nice feature that I really like is the ability to add additional watch faces, which is not something common with low end smart watches. The watch comes with 3 built in faces and has room for one more face which you can download using the app. There are hundred or more different watch faces to choose from, although you can only download and use one at a time. The available faces are updated periodically, with some faces removed while new ones are added.Another neat feature that is common with some smart watches is the flashlight mode, which emits bright light from the screen, providing with effective short range lighting. Not as good nor strong as the light a smart phone emits under the flashlight mode, but better than nothing.Update - May 10, 2021After a year of use, the watch is still working well, doing what it is supposed to do. The only issue is that it sometimes loses the bluetooth connection with the iPhone (still the old iPhone SE). A bit annoying as each time it occurs some of the settings, such as the notifications, measurements and steps goals are reset. On the other hand, it's easy to set in back, so although annoying, it's not a big deal. I will replace the watch eventually, since newer cheap smart watches have more features and larger active screens, but at about $30, it has been a very good investment.
