Customer Product Reviews

Rated 2.7 out of 5★ by 21reviewers.
Rated 5 out of 5★ by great, a little small screen 07/18/2012
Rated 1 out of 5★ by Great watch....that's about it. I purchased this watch from Mishawaka, IN, for purposes of keeping track of my heart rate while working out. I read the reviews and 3 stars looked good enough for me to spend the money. MISTAKE. I do not mind that you must hold the heart rate button down for several seconds before it reads, but what I noticed on mine is that after I set my Profile for my Age - 25 and my Gender - M, the watch took even LONGER to read, and most of the time does not even give me a reading, it times out! I wore once during p90x, and not one time for the entire hour of the program did it want to give me a reading. I was not overly sweaty, tried wearing the watch at a snug and loose position, moved it around, etc...No such luck. This product was a dud for me and I will be returning it for my $28. THIS WATCH WILL JUST WASTE YOUR TIME!! 1 STAR from this customer. 03/21/2013
Rated 4 out of 5★ by Great for those trying to lose weight! This monitor exceeded my wants. It tracked my calories burned while doing Insanity. Its a lot better than guessing using the LoseIt app! I will log the usage on 01/24/2013
Rated 2 out of 5★ by GREAT PRICE BAD WATCH I bough this watch to help count calories that I burn doing Tubro Kick and Insanity. Well the calorie counter has stopped working after 1 1/2 months. I will not buy another onf these. 04/29/2013
Rated 3 out of 5★ by Still deciding The jury's still out after 1 week of use. My big discovery today though, which could be a gamechanger, is that your pulse is apparently measured thru the button you push on the face of the watch, using the pulse in your finger or thumb. I has assumed it was thru the back plate of the watch. After a very frustrating outing today when my pulse never registered, I learned that wearing gloves was the problem. You need a bare finger. Keep that in mind when the instrument frustrates you. I don't know why that wasn't mentioned in the instructions, as it gives you a whole new way of looking at it. 03/03/2013
Rated 1 out of 5★ by disappointed I was very disappointed in my heart monitor/watch. The heart monitor portion stopped working the 3rd time I used it. It worked perfectly the first two times but the third time my heart rate never came up, it would just go back to the mode page. I will not buy this product again. 01/13/2013
Rated 1 out of 5★ by You get what you pay for! Took it off after working up, went to bed and found the calorie counter still counting away as if I was wearing it, this watch is anything but accurate. Not going to use it again. 01/17/2013
Rated 1 out of 5★ by Unsatisfactory The monitor gave very erratic readings and I returned it to my local Walmart. 07/03/2013
