While I have only used this item for two weeks, it has worked perfectly so far for me. I don't even find it necessary to wet the back of the chest strap as the directions indicate, it works great for me as soon as I put it on. I average running 4 - 5 miles per day, about 5 day a week. I have read that the battery life isn't great, but the batteries it uses are about $4 for a pkg of two so even if they don't last that long it isn't a big deal.Get more detail about Timex T5G941 Heart Rate Monitor Watch.
