My metal pointer broke after 15 years of use. I bought this because I thought it would be better, firstly it's very slippery, especially when you sweat and climb stairs. The plastic inside the case is very thin and after a while the drill bits fall into the holes and are difficult to remove from where they are. but I don't think I can use it for too long. In addition, since it is a sealed block, it retains moisture, and a small amount of moisture inside will cause the drill bits to rust. I will not buy this style again.
