Chinese Fitness Tracker Automatic Heart Rate Tracking

Although the most expensive of the fitness tracker watches, it worth it for serious trackers. Highly recommend.

Series 6 health features are worth the purchase price alone. Watch does it all including fitness tracking.

Does the job. Gets notifications and tells the time. Don't use the fitness tracking so can't comment on that. Battery life is kind of disappointing. But still lasts about 10 days

I really love iOptron SkyGuider Pro star tracker. It's easy to use and has provided great tracking for me so far, giving sharp stars using my DSLR. I wish the polar scope light would stay on all the time, rather than the declination bracket having to be in a certain position before the light comes on. But, it's a small inconvenience and I think it's outweighed by all its positive points. All-in-all, a great little tracker that's portable, affordable, and very capable.

Is a great, cheap and easy solution to strap a vive tracker on my shoe for feet tracking in virtual reality.

This watch has some many useful function including calling for help if you fall, heart rate monitor and other health app. I feel like Dick Tracy when I speak into my watch using the intercom or answering a phone call.

This is the third Apple watch I've owned. It seems that this watch works a little faster than the others. I use it as much for health issues. The Heart Rate monitor picks up the same as my belt. This is an improvement over the past watches. The Blood O2 is good, particularly now with Covid as lung function is an indication of the virus. All in all it's a worthwhile purchase.

This watch is absolutely perfect for my husband and I. We aren't sports fanatics but need to keep track of heart rate. We walk, ride bicycle, and treadmill. This watch tracks it all. Best of all, we only have to charge once every 3-4 weeks. Just wish I could get another one in the white rock color.

Great unit. Automatic pairng, just plug it in and go. Good quality sound, of course function of bit rate and quality of sound file. I haven't even read the instructions, just plugged it in, turned on Samsung Galaxy S7 smart phone Blue Tooth, and started listening. Nice -- super fast free shipping, I love B & H

My wife and I both game with PS5 and the symbiosis between PS5 and the high refresh rate and automatic HDR controls were the primary reason to upgrade. It makes our Living Room. Can't describe the picture quality, as it's "see to believe" good. I stream through the PS5 so I can't comment on the Smart TV functions, but I p[layed around with the guide, and 'Live' channels built in, and it was comparable to cable.
