A total waste of money. You can't hear the bell even if you have it clipped to your body, the vibration feature didn't work and the timer has a mind of its own. I smashed it with a pipe wrench and felt good afterwards. 1 star

Broke within 1 round. Quite possibly the worst built product I've ever purchased. 1 star

I bought this one because I figured if it broke I'm not out much money, I figured I might get lucky but I didn't. Sure enough the other reviews are correct, it is very cheap and very porely built. The batteries don't fit in well and the cover to them is tough to keep on. It worked for about 8 work outs and then it just went nuts and even by adjusting the batteries it won't work right. Save the 10 bucks and buy something different. This is a terrible product. I can only imagine how many of these end up in the local land fill within a month of purchase. 1 star

The idea was good, but Everlast failed in the execution. The bell is so low you cannot hear it, and the vibration feature is so weak, you cannot feel it unless you're holding it in your palm. I'll probably try a timer from another manufacturer. I assume that Everlast has different lines of products for people that are in the business of boxing, because what they sell to average consumers is of poor quality, including their corny DVDs. 1 star

It worked great, for a few weeks. Now it just does whatever it wants to do. A piece of junk. I also got a pair of bag gloves from Everlast (they should throw an 'N' at the beginning of that) that fell apart after two workouts (even my inflated sense of self refuses to believe I hit that hard). 1 star
