Heart Rate Monitor Failure Sound

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.

I have never been disappointed in the results I've had with Verbatim media. I've had about a .5 percent failure rate. Can't say the same for other brands I've tried.

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 was somewhat concerned by other reviews about some quality control issues with these units. One out of four that I ordered did not communicate with the controllers in radio slave mode. I returned it and it was promptly replaced with one which did. I bought 2 kits with controllers, and 2 single units. Having seen some of this manufacturer's less expensive units I was happily surprised with how well-built these units are. While I don't for a moment discount the significance of a 25% (20%, if you count the replacement unit) failure rate (how can they stay in business at that rate?) I can also say that they do all they are advertised to do, at a fraction of the cost of other radio controlled units. At a cost of less than 1/6 of a name-brand unit, I can even afford to risk a failure (or accidental destruction) in one of these at a rate I could not sustain with the name brands. I have been able to work up a protocol for ganging them with my older Bolts (and presumably any other unit which will fire on an optical slave) which is efficient and gives me more functional units. It works even when the purely manual units are within a sealed environment such as a softbox designed for use with speedlights.

[This review was collected as part of a promotion.] Good product, very fast speed and 0 failure rate so far.

There are many brands of drives that I avoid for their high failure rate, and as they increasing become manufactured by the same company, it can be hard to avoid the,. Synology is new to me, but anything is better than the popular brands that I KNOW are going to fail. We'll see how it goes over the long term with this one.

I am hoping these will be back in stock as I use a lot of these and love that the failure rate is very low - maybe 2 out of 100 or so - not bad compared to outer brands.

I previously went through a couple of hundred Mitsui/Mam-A discs, which had a reasonable but still detectable failure rate; so far these have been flawless. Burn rate is relatively slow, which seems normal for archival DVDs. Packaging states they're un-compatible with 1X/2X speed drives.
