This product is unreliable. I used it one morning and it registered my pulse at 68. I took my pulse again a minute later, without moving from my bed, and it registered at 178. After that I tested it again and again, and the pulse reading wildly flucuated for no reason. I can only assume that it is not really reading your pulse, but is just giving you random numbers.

Pretty much useless for physical activity. You have to be sitting still to get a read.

Works fine. Don't press you finger down too hard or it will give you an error.

No! Do not buy this product. I completely wasted my money on it and it has never consistently worked since the first day I got it.

I bought this to wear around my neck for taking my heart rate during jumproping or spinning. It seemed like a great concept, but it never worked since I opened the package. I cannot return it now, because I should have called Amazon right away, but I made the mistake of putting it in the drawer out of frustration.

I even read the directions with my aerobics instructor, and she could not get it to work. She said she just uses her watch and I looked at her and laughed!

The good old fashioned way of checking our heart rate is the best, and I should have saved my $20.00 instead.

Don't buy this product unless you want to waste your money.

The Tanita 6102 is fast and reliable. It typically displays a result in only a few seconds. I have tried several heart rate monitors, and I found that this works faster and better than the more expensive models. It also is capable of displaying higher rates than other monitors.
