Optical Heart Rate Monitor Accuracy Review

[This review was collected as part of a promotion.] The refresh rate and accuracy of this monitor is top notch. I absolutely love it. My only issue that I have is that every so often, it doesn't turn on and I have to unplug the cable from the power block and back in again. The power block is typically super hot when this happens. Not sure why it over heats like that as most of the time I find this happening is when I haven't been using the PC and the monitor was off for hours. Doesn't make sense to me but take that out of the equation and it's AMAZING!

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.

it has ok color accuracy and good response rate

Great that he can monitor his heart for afib and take an EKG whenever he wants.

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.

Quality product. If you are serious about color accuracy across your equipment from monitor/ambient/print review, this is a necessary part of the solution. I installed this bulb in a architect lamp with a Lutron dimmer. I now have an absolutely reliable light source to evaluate the accuracy of my photo prints. Makes a huge difference.

[This review was collected as part of a promotion.] I've been using this monitor for 3 weeks or so and I really love it. The color accuracy is great, the picture quality is also top notch. The back lightning is a nice touch , I couldnt be happier it it :)

Incredible color accuracy and HDR; the local dimming is a wonder and the 240 Hz refresh rate is sure to add to the experience. At the moment this is my favourite monitor

I am very happy with all aspects of the lens - optical quality, focusing speed and focusing accuracy. The 135mm focal length is great for portraits and also will be useful for low light events.
