Polar Heart Rate Monitor Watch Change Battery

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 change the way a watch films. The bass from this sub is incredible.

[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.

Yes you will get some bass roll off in the very very low end, so it will not go down to 5 hz like a set of 800.00 aphex 124a or 750.00 Arx distribution split. The 20 db of gain is a big plus, and of course having level control pots on all outputs, is an excellent feature. IF you are using to drive multiple low end subwoofers, you may wish to change the output capacitors. Existing ones are 10 uf 50 volt polar electrolytic, and you can easily change for 100 uf 50 volt polar electrolytic for a few dollars. Once you open the case these can easily be seen. The capacitors are easily available and are not expensive. If you try this you will need a solder sucker. Do not try soldering without one. Suck up all the old solder and remove the caps and replace all of then in the existing threw holes. They are marked for positive and negative on the pc board. Once you got them all in place just solder them back in. Once you do this for a few more dollars you can rival any expensive distribution amp. Would be nice if it was more than just 3 inch deep on the case. Most components are at least 6 inches.

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