I dislike the fact that, the magnet that holds your bit in your screwdriver, will be stuck to the bottom of the bit when you remove the bit. I put a different bit in my screwdriver and went to use the screwdriver, and a bit fell out. I had to realize that my little round magnet was stuck to the bottom of the last bit that I had used. I pay attention to this now. I make sure I remove the magnet from the last bit, and put it back in the screwdriver. this is why I gave the rating of four stars. When that bit falls out while you're using it, it could be dangerous.
