I got one of these after misplacing a similar one that I bought at Wal-Mart. I found the Wal-Mart one and it's working fine, but this one didn't work long. I like the style, and the expansion bracelet fits my big wrist well, but I've put two new batteries in it and it still doesn't work. I see that one of my options is to return it, so I probably should do that.
