Microsoft Band 2 Heart Rate Monitor Accuracy

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 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!

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.

The dual band delivers and I was able to capture excellent images of Rosetta, Heart & Soul and Horsehead nebulas.

Angelbird 256GB AV Pro UHS-II microSDXC Card U3 V60 A1 (ANP256MSDV60): Purchased from bhphotovideo.com, shipped by bhphotovideo.com, purchased on 24-FEB-2021: The microSDXC card and adapter come in original packaging. All items like on the B&H pictures. The card works very well. It becomes medium hot during writing and reading. Like for most cards recently purchased and tested, the card should be formated with full format and test/overwrite of full capacity (not short/fast format; this can easy take few hours). And/or a complete writing/reading test of the card should be performed using specialized software, e.g. H2testw. This will ensure full capacity available and relocation of bad sectors by the electronics of the memory card. This will ensure that during normal operation data get not lost and to prevent hang-ups of the card during writing. Unfortunately this conditioning of cards is often not more well done during production of cards. Tests with H2testw v1.4 on Microsoft Surface Book 2, exFAT 32kB cluster size, internal SD-slot (SD-Adapter with microSDXC card): Capacity 241342 MByte, Continuous write rate 102 MByte/s, Continuous read rate 134 MByte/s.

After employing a Microsoft keyboard for some years it is very nice to have a keyboard designed for the Mac.� The Microsoft keyboard is also top rate, but because it is designed for a PC system the keys do not always match up with the Mac.� The Das Keyboard 4 Pro for Mac is an excellent tool I would not hesitate to purchase again.

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
