EpochAir Fitness Tracker, Waterproof Activity Tracker, Smart Watch with Heart Rate Monitor, Sleep Monitor, Pedometer, Calorie Counter Sports Fitness Watches for Women

I bought this as I really want a SPO2 meter to monitor oxygen saturation in my blood. Of course, due to Covid19, all general SPO2 meter are oos or over-priced....Then I came across this product, same price of those over priced meters, but with much more functionality and better looking, why not?For SpO2 monitoring, it works great. The reading is within 1% difference when compare against my roommates' Samsung S9 phone.For other features, it also works flowlessly. Can monitor heart rate, blood pressure (didn't test this one, as I don't have any thing to compare with, and I will not suggest any one to rely on such a small device for blood pressure), sync time with phone, play/pause music playing on the phone, receive notification (even show skype message directly on the watch face!) What else I can ask for? Oh, just one thing, hope the whole screen can be touch screen, instead of the single buttom below the screen (maybe to much for it's price :).

I read a lot of reviews on many similar products before deciding on this watch. I purchased it with the understanding that it would be difficult to work. That being said, I use the app on my phone for most things like checking heart rate and blood pressure. I can get my heart rate recorded using the watch itself, but the app is easier for me. I checked my heart rate manually right after using the watch and it was at the same level the watch had recorded. I mostly wanted to use the watch to track steps, which it works well for. It does have to be on your wrist to work, it can't be placed on your belt loop or hung inside your apron while cooking to prevent germ spread as I had hoped. The sleep tracker doesn't seem to be accurate, as I wake up to go to the restroom throughout the night and it is never recorded as having woken up. The watch face also has a bright light that flashes when you turn your wrist to check the time, which is great when that's what you are trying to do, but at night wakes me up. The battery life is pretty good, though if you go for a 3 mile walk on half battery it will die. Since I don't use the sleep tracker I have taken to charging it every night. I'm very happy with the watch, but I really only use it for steps.

I purchased this on June 15th and it was okay. This was not my first smart watch and I honestly didn't like the way the screens were set up; they were rather hard to navigate. I downloaded the app and paired the watch without difficulty and found the watch to be accurate. It has a comfortable band in the standard 20mm size with a quick release, making it easy to use different bands if desired.Even though I didn't like the screen navigation, I would have kept this as it has all the functions I wanted, including heart rate, BP, and O2 sat. It was not only waterproof, but it includes swimming in the sports tracking, which is not easy to find, especially in combination with O2 sat.The battery life was very good and lasted nearly a week with normal use. However, the first time I had to recharge the battery, it stopped working properly. I was able to see the watch face screen, but none of the other screens. Instead, it showed me a few other screens, shown in the photos I've attached, that were obviously not supposed to be there. I'd see the first one and after long pressing it, I'd get the next one showing the green, red, and teal bar. Pressing any of those only led back to the previous screen showing 00:04:58 with the 4 other 0 value measurements.After trying to get anything to work on the watch for about a half-hour, I arranged for a return and refund. This process was very easy to do. UPS brought the pre-paid shipping label to my home when they came the next day to pick it up. Within a day of shipping the watch back my refund was credited to my Amazon account.I hope this review helps others. I do think it's worth trying this watch due to the features combined with the ease of the return and refund process.

I love the smart watch. It is good value compared to expensive brand ones. It comes with manual and easy to set up. It is waterproof, monitor heart rate and sleep and long battery life! I do exercise more after I purchase this fitness watch! I am very happy for this watch and will purchase for my daughter!

I was very pleased with this when it arrived. Now I am quite unhappy. I should have know, you get what you pay for. My screen will no longer show anything - unless it is plugged in to charge.

Your browser does not support HTML5 video.  Initially I really liked it. It has a great design and fits well. Looks very similar to the Fitbit Versa at a fraction of the cost. I’ve had it a few months and it has still held up but the steps aren’t even close to accurate. Interestingly enough, the BP & heart rate are decently accurate. The reason that I’m rating so low is because the step counter isn’t accurate nor is the sleep. It’s actually impossible to sleep with this thing as anytime that the face touches anything, it vibrates and wants to shutoff. It also doesn’t have any buttons. Only touch screen. You get what you pay for.

If you tell me how to send it back I will!! Second time charging I thought I just didn't have the prongs on right.Wrong. The darn thing just won't charge. I bought a cheaper watch that works better than this.

It’s not bad, but I was expecting perfection after reading the reviews. The touch screen is super sensitive and there’s no way to lock that so it’s not constantly being touched into the next screen. I really haven’t figured out how to turn it on after you turn it off if you don’t have the charger, I got it, but I don’t know how I did it. I also can’t get my notifications to alert me on my watch and when I turn off the apps I don’t want coming through on the app, those changes don’t save and they’re continually turning back on. The price was great and I’ll probably just give it to my daughter now. It looks good and is super comfy, just needs a screen lock when you’re not using it and glitches like notifications to be figured out.
