I purchased a similar item (with a permanently attached handle) about 10 years ago. In the past couple of years it has lost 3 teeth. Despite that, it still works perfectly. However, I figured in time more teeth will fall out and it would become useless. But what really led me to this purchase was the power drill adapter. This makes an extremely useful tool even more useful.It's a no brainer to install and use. It's functionality is unlimited within its intended use. I highly recommend this gadget. You won't regret it...and you will use it more often than you 'd think.
