The watch is light-weight, comfortable, and helpful. For a first-time fitness watch buyer, I am impressed with the calorie counting feature and the heart-rate monitor. I do wish that it had a back light though. Recommended buy.

I live in Rio - Brazil. Bought this item on Nov 6th and received on the 17th at Good Deal Electronics. It is a very nice watch, good design and very easy to use. In fact I managed to start using without reading the manuals. Another great advantage is the size. I guess It's smaller than the mid-sized ones. Good, since I don't like big watches. I am very happy with this purchase, which was a good deal!
"Good basic HRM/watch"

I have owned this product at least a year. I have not yet had to replace the battery. It is a good basic watch. My main problems are that it is always on...you can't turn it off when not using it (the watch feature is always on) and that there is no backlight which makes running before dusk/after dawn difficult.
I bought it for my wife. Easy to use, affordable, reliable, confort to use and easy to read.
"Stops working accurately"

I've owned two of these watches and both of them stopped reading my heart rate accurately within a few months of daily use. While running it will start out giving an accurate reading, then start jumping around, giving me an impossibly high (151 at a slow jog) or low reading (71 while running uphill) or it will jump from an extremely low to an extremely high heart rate (51 to 160) in a second, a virtually impossible reading. It's maddening. For some reason, I do not have this problem while working out indoors at the gym. Only when running outside. It's too bad because it's easy to use. But what's the point of a heart rate monitor that reads everything but your heart rate.

First, if you buy one of these be aware that it's extremely easy to accidently wipe out all the personal and cardio info it stores. There isn't any way to lock this monitor to protect such loss.
I sent this monitor in for repair. They emailed me to tell me they received the monitor. They emailed me to tell me they replaced the circuit board. They had my monitor over a month. I got this monitor back and it works exactly the same as before I sent it in. They did nothing to it. Yes I know how to read and I always read the manuals for everything I buy. This monitor does not display the time when brought to the transmitter belt like it say's it will in the manual. There isn't any way for me to have this display the time while it is monitoring.
