Fitness Tracker With Most Accurate Heart Rate

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

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 tracker for medium set up. Polar alignment is very simple and tracker is very accurate without a rracking scope.

It's hard not to rate this 5 stars. It does it's job and I get accurate white balance. It was also very cheap compared to other white balancing products. I am very happy with the results.

Most of my work is portrait so I need a good prime lens around this focal length. I considered the Nikkor equivalent but after reading various reviews I decided to give this one a try. I'm glad I did. Wide open the DOF is almost non-existent at close focus. You can use that to your advantage of course but it comes at a price since there's no AF to rely on. That's no problem for me as I've been using MF lenses for years and I trust my eye. But if you're not a MF veteran you may find the need to focus inconvenient. (Like other reviews have said the focus confirm chip isn't always accurate. I suspect there's a manufacturing spread on this and you may get lucky and receive one that is always accurate.) Technically the optical quality is outstanding and I can't add anything new here to what others have already posted.

Good stick, very accurate compared to other sticks in this price range. Most economical option for dual stick setup in space sims.

I love this camera with all my heart.

This little light is big at heart!!
