ZKSSGY Fitness Tracker

Honestly not bad at all! I decided to save a little money and go with this over Fitbit because my Fitbits kept crapping out after about a year. I’ve had this for a while now and it’s still going strong! The battery lasts for about a week before it needs to be charged, even with daily wear! The screen is vibrant and easy to read. It was a little confusing to figure out the taps and swipes and that’s probably the worst aspect of the whole thing. Comes with an app that shows your daily activity. When you’re on a walk or run, it tracks in km while you’re active but shows in miles when you’re finished. I find this a little weird, and not desirable, but not a deal breaker! I’m a heavy sweater, and that hasn’t seemed to affect function. I even wear it in the sauna and it doesn’t overheat or wig out

I use it to keep up with my steps. It also syncs with my phone. Makes self accountability very easy.

The step tracker/distance seems pretty accurate. The battery lasts for days. You can control what notifications you get on it which is nice because I just want texts. It seems pretty accurate tracking my sleep too. A lot of good wallpaper options! It’s not advanced data tracking but it has what I need. However, this tracker doesn’t have a timer. I would use a timer all the time. I do wish they had one with a sport/stretchy band instead of the silicone but that’s just my personal preference. The silicone can bother my sensitive skin so I have to clean the band often.

Doesn't sync with my phone (Pixel 8 Pro) unless I manually open the app. I have to do this occasionally to correct a slight drift in the time. This makes it useless for getting notifications. Otherwise, does what I want, which is monitor my heart rate, blood pressure, body temp, and blood oxygen. I assume these are all accurate. The numbers look believable. The sleep tracking function is garbage though. The screen is very readable and has a number of nice layouts. Setting it up was easy enough. Then again, if I'd wanted a proper smart watch, I'd have paid a LOT more money. When this one bites the dust, it's a coin toss whether I'll buy another.

Excellent little watch. Easy to connect to device via bluetooth. I personally hwve ,y daughters picture as the face, lots of choices to choose from. Pretty accurate reading. Heart monitoring works well. Fitness tracking as well. Sleep tracking works, but if you go to sleep later than 3xp3cted it starts tracking the sleep if your arm is still.

This tracker does not perform as expected. I bought this looking for a simple heart rate monitor while I walk, as I sometimes get dizzy when I exert myself. I don't need the other features, and initially I thought they'd be nice to have anyway. I should have listened to all the negative reviews. When it arrived, I charged the device and installed the app (mountains of bad reviews there as well). I read the very limited instructions and decided to give the tracker and app a try. The app is called K 3 3 p h 3 a l t h + (3's are e's, no spaces), I find it suspicious that there is no mention of the app for reference. It's only after the device arrives that you can go look at the app and it's reviews. Initially, the watch band was a bit small. I could only reach the 3rd hole from the end of the strap. The heart rate monitor took about 10-15 seconds to read, and showed 60 bpm while resting. Maybe a bit low, but maybe not. As I was brisk walking that evening around my local park, 10 minutes into the walk I checked the tracker. The sport tracking feature showed the time elapsed since I started, but showed 0 steps and -- for heart rate. I kept walking and switched the tracker to the heart rate function. After 15-20 seconds of continued walking, it returned a value of 90 bpm. That didn't sound right, so I took a manual reading and found 136 bpm. Wildly different. This device is so inaccurate as to be useless. In returning the device, for some reason I had to provide my own bubble envelope to return it. Just an extra hassle I haven't experienced when returning things to Amazon before.

Meh. Cheap. If you can afford it, upgrade to a Garmin Venu3. I suffered almost daily frustration with buttons that pressed too easily, low battery life, inaccurate step count, display that didn't come on sometimes.

Comfortable watch, and I don't like wearing watches. The fitness data seems fairly accurate. I got it to track heart rate specifically. I like the numerous face designs. The app is pretty good, too, compared to other budget fitness watches I've tested. I do construction work with this on and have also worn it in the shower and swimming. It's never failed. I did end up picking a watch face that shows battery life prominently, though. It lasts days (almost a week?) between charges, but I often forgot and then woke up with a dead watch. So now I just glance at the bar whenever I raise my wrist for the time or my heart rate.
