Polar A3 Heart Rate Monitor Replacement Watch Strap

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.

I like 75Hz fresh rate of this monitor as you can watch video at 75Hz to get smooth experience. The color accuracy is great to me as it's a IPS panel. All in all, this is a great monitor.

This is my first Apple Watch, so I did my research. I decided on the Series 6 due to the heart monitoring features. I ordered it from B&H because their price was good (they also threw in a free watch guard) and they are a trusted company. I was afraid if I ordered through Amazon I might not get what I ordered. I have had the watch about 3 weeks now and am very pleased with my purchase.

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

[This review was collected as part of a promotion.] Using this tv to watch sports brings better quality and hearing the game to a more serious level of awesome. Clear visual makes it look like you're right there. The sound with adding a bar brings your heart pounding with excitement, a bit loud for the kiddos but for the kid at heart not a problem.

I had another brand of star tracker that my toddler got her hands on so this was its replacement. The polar alignment camera with this setup is amazing. All my subs are spot on from one to another which I had difficulty attaining with the alignment scope my other tracker had for polar alignment. I'm using a DSLR and a 135mm lens. Pros: Small size for easy transport. Polar camera makes polar alignment very accurate and easy. Tracks like you would expect it to. Built in chargeable battery. Cons: No way to control camera shutter without an additional hand controller which is sold separately. You'll need an intervalometer if your camera can't do multiple long exposures by itself.

This is a replacement for an older one I had that was USB-A and micro USB. The transfer rate on the old was good, but this is much better.

I love this monitor. It was easy to set up and the instructions were prefect. I'd buy another one in a heart beat!
