## Description

smart watch

Review: I purchased two of these watches recently, one for myself and one for my girlfriend, and was surprised at the advertised capabilities given the price. However, it was not long before I realized the true quality of these products. Use. We tested these watches on both wrists with varying tightness, but generally a firm compression. Battery life. The battery life seemed strong, lasting 3.5 days with it's first 100% charge. However, this became oddly inconsistent. The second 100% charge only lasted 1.5 days. The third 100% charge lasted ~3.5 days again, but only for my watch since my girlfriends watch was no longer able to charge. This fluctuation occurred without changing settings or general usage. After the third charge however, both of our watches cannot charge at all resulting in the expiration of these watches. We tried resolving this issue with different charging units and online help. No abnormal activity, water damage, drops, or damage of any type had occurred to either of these watches. Health Tracking. SLEEP TRACKER. We charged our watches during the day since we were most interested in the sleep tracker. The sleep tracker consistently told me I was sleeping "perfect" and was getting between 7-8 hours of sleep. However, it stated that I went to sleep 1 hour before I even laid down and told me I woke up when I started walking, not when I actually woke up. It also failed to track my constant sleep disruptions and waking up in the middle of the night. I have a spinal injury at the moment and this is not uncommon for me during this time. This gave us wildly inaccurate data, rendering the sleep tracker useless and misleading. STEPS. I walked side-by-side with my girlfriend on a few brief 'walks' and also had a tracker on my phone. The data was different by about 20%, between the watch and the phone, but it is impossible to say which one was inaccurate. Therefore, I cannot speak on the accuracy of this feature. No other features were tested on these watches by us. However, given the integrity of the watch so far, I would not trust the data personally. I did enjoy the reminders for drinking water... Bluetooth functions. My watch occasionally disconnected with my phone, but it seemed to "catch up" with the data that the watch tracked when it would inevitably reconnect. However, these constant disconnections made the convenience of phone notifications on the watch sporadic, which was a little irritating. OVERALL. The health functions are either wildly inaccurate or questionable at the very least, but some data could be determined useful. However, since not one but both of our watches did not last more than 2 weeks, with constant errors and eventually losing all function, I can definitively say that these products are not worth even the low price that they are sold for. Had only one of our watches had these problems, I would presume that it simply had a manufacturing defect, attained a refund, and tried again. However, since both of our watches showed great disfunction, I would presume that this is simply a poor quality product.
Review: The watch lasted me 9 months until it stopped working. I bought it primarily to track my swimming, which it did pretty well. The waterproofing is good, I never had any issues with the watch returning to normal use after a swim, which is my main form of exercise. It also worked well for tracking cycling and other supported forms of activity. The features of the watch are nice and convenient, being able to enable selectively the motion detection for enabling the display and quickly move it to a do not disturb mode. Total silence mode is hidden away in a menu which is less ideal, but it's good to have that option separate so that you can still have alarms work properly if desired. The step counting sometimes caches its result making it jump a few dozen steps at a time, but it seems to track accurately. The heart rate can give you a general idea of activity but it's not reliable in any accurate quantity. The sleep tracking function requires that you wear it to sleep (of course). The battery life is fantastic -- I usually only have to charge it once every 3 to 5 days. The issue I encountered after 9 months is that the screen started having phantom touches on the screen. These phantom touches would lead to several features misbehaving, like the homescreen swapping to different backgrounds randomly, or trying to run a timer and it pausing and restarting randomly. After a couple days of those touches, the display started rendering incorrectly as if there were an overlay burned in that displayed a bunch of zeroes all over the screen. Eventually the watch started finding phone when I just had it on my wrist without interacting with it, which is when I had to chuck it in the trash because a silenced phone ringing during work was problematic. I won't be buying a second one of these because for the price point, I expected to get at least a year's use out of it. The app that it connects to is terrible. I left a more detailed note on the play store, but some highlights are that it doesn't track swimming properly because it's not one of the app sports even though it is a sport you can track on the watch, it will import your steps that the phone counts and double count the watch, inflating the step count, the translations are terrible and sometimes completely missing rendering some text in chinese, and the gps will stop tracking after 30 minutes of any sport like cycling or running, then display your final destination as having travelled to that ending point at 99.99 mph. And that's not even half of my complaints about the app.

This is fine if it was just a digital watch, but as far as fitness tracking goes it was kind of a disappointment. I would say that the positives are it does have a plethora of functions and the battery life is pretty solid. It also has a lot of the capabilities a smart watch has which is ok. For me, the negatives outweighed the positives. Even though this is a passing grade smart watch, its health and fitness tracking is where it falls short. I don't need all the bells and whistles, I just need a close to accurate analyzation on my heart rate, my steps taken, and my calories burned. Didn't even care that the sleep tracking wasn't accurate I can do without. The three simple things I was looking to track the most accurately was definitely not close to accurate. The heart rate tracking is a big one for me. I spend a lot of time doing cardio and like to see the bpm numbers as I am doing the sessions. Almost each of the days I had this on doing cardio, my heart rate was easily mid to high 160s bpm (I know this from experience of doing cardio and knowing my body. Just wanted to say that before everyone is like "maybe you weren't working out hard enough" lol) and the fitness tracker would never register above 98 bpm ever. My heart would be pounding out of my chest and the fitness tracker is just showing 80-90 bpm. So this was kind of a let down. Next issue was calories burned. I would have this on all day and it would say I burned 200 some calories for the day. I burn that if not more just on the treadmill before my weight training and I work out in the morning and am active all day. The steps aren't accurate either. Ill be on the treadmill for 5 miles and it only registers like 300 steps. Sleep tracker also not accurate. If I slept for a lot it would register that I slept for a little, and if I had little sleep it says I have slept a lot. So meh lol. Again don't need all the specs but the inaccuracies for the three basic things is what did it for me. I took it off and put it in the drawer where it will likely stay. I wear nice watches so this literally serves no purpose for me lol. Hate to leave a blah review just being honest. Thank you!
