Polar Bluetooth Heart Rate Monitor Battery Size

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.

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.

If I turn on my Bluetooth Emoji heart perfect sound for my music Pandora

Great resolution and a decent refresh rate. Probably the maximum size I would want for my desk where the monitor is at arms length.

Great rechargeable battery! Can't really rate it yet. It is my backup battery. I will know more when I need to use it!

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

This is a fantastic piece of engineering. I love the size and the battery life is stupendous. The Bluetooth tech is near-flawless, only having fits every so often, but that's typical of all my wireless devices (and this is better than most). The fidelity is astounding, however, it's not a super-loud speaker. This still works for me since 99% of the time I'm usually indoors with it anyway. Ultimately I recommend it, but if you're wanting to split eardrums, you may want to consider the MegaBoom instead.

I found these bluetooth wireless earphones to be the best I have had the luxury of owning. Luxury due to the relatively high cost yet the best sounding earphones I own. I have many other BT earphones which were released when Apple announced the new Air-Pods. I own versions in the $30-40 range up to these $270 Powerbeats. I find these to be the best in sound quality, comfort, secure fit and battery life. So much has been mentioned about the size of the storage / recharge case. This is not an issue for me and besides if you look at the size of these earphones, it becomes obvious as to why the case is as large as it is. The battery lasts long enough for me to not worry about carrying this in my pocket and certainly a non-issue when carrying other things which require a backpack or something similar. Great headphones. I highly recommend these.
