This has a very slim profile. I also likes the fact that the battery lasts for 15 days and chargers in 1.5 hours. Aside from maintaining an accurate time, the feature I use the most is step counting. Notifications for phone calls and texts is another plus. The oxygen saturation is accurate, the heart rate is reasonably accurate, but I do not think the BP is accurate. I always get the same reading at rest or when I am active. I do not use any of the other apps on the watch. Great watch for the price.

The watch meets my primary need: tracking my steps. I'm fond of its appearance, and I appreciate the ability to customize the home screen. However, I discovered on the third day that adjusting the exercises and the home screen requires holding down a button, which felt a bit unintuitive. Regarding the sleep tracking feature, I'm uncertain about its accuracy. For instance, I went to bed at 9:45 pm, yet the tracker indicated I was still awake at 10:10 am. On the other hand, the step-tracking feature appears to be quite precise.

My old fitness tracker, similar to this one, had major issues after 6 years of use. Yours is closest to the one I had all this time that did the job. The new App is different and more up-to-date so it will take some time for me to get used to it, but right now I am happy with the new tracker and App. Time will tell if it gives me what I want. The price was very reasonable. It took me a while to figure out how to see it update the information in the App. I discovered this by accident. I think that once I get used to this device, it will do what I want. I would love 3 new black tracker bands for free.

I have tried so many smart watches since January but this one is a keeper, so far. Others have been good for some uses but had their faults. This one is smaller, has less features than the larger ones but for my purpose is working well.
My main uses for these watches are the water and sedentary alerts, for medical reasons..I have to add that the vibration for these repeats 2 or3 times and there is a slight jolt. Gets my attention.
The other is the steps counter. I don't use the exercise ones and am waaay past the need for the female readings.

After trying so many watches, I have come to the conclusion that the app is the biggest problem, not the watch itself. This watch has a different app than the others. I have a sketchy wifi connection and if I walk away from my phone to the basement or another room and come back to the phone, check the app it will read disconnected. Just a few seconds will automatically connect and the data will sync from the watch. That kind of pairing has never happened with other watches and the couple of common apps that so many others use.
Most of the watch faces are not worth much, half are childish and the others are dark and not very attractive, too many holiday ones also. In fact, the screen is a little too dark and there is no way to brighten it and also no way to keep it on for longer than a couple of seconds. I can live with that because it has the features that I really need which work quite well. It does wake up quickly when I move my arm. The blood pressure reading is not accurate which is true of the other watches. Don't know why some continue to put it in. I checked oxygen level and heartbeat against the finger thing and they were within a couple of points of that.
The phone and SMS alerts seems to work but I don't get a lot of those so I may not even pay attention.

I like the size and weight of the watch, it is quite comfortable to wear, I have a small wrist so I imagine someone with a bigger wrist would be even more comfortable. But that strap is so hard to pull off to get to that charging tab I'm always afraid I will break it. It has kept the charge for 4 days.
I can forgive some of the features that aren't on there that are on the larger ones because this one works for my needs. I can't comment on the exercise readings because I don't use them. but for the money I think it would be worth buying this and checking that out.

Best to carefully read the seller descriptions and Q and A's for a more detailed description. I will just say that it is working so far and I hope continues.

Fairly accurate readings. Has extra features, like mood and blood pressure. Don't think those are super accurate, but close. My wife enjoys hearing my mood score. Disappointed the app doesn't give weekly or monthly totals, just a graph. Fits and charges well.
