"The item is very clever and I'm sure quite useful if you have the right bits. However: this is meant for longer bits, such as double-ended bits for a manual screwdriver. In my case, I wanted it for short bits and this didn't work at all. Bits fell out easily when tin was tilted, and it was hard to remove the bits. Fortunately, I ordered several of these products at the same time, so I was able to use a different one for my purposes."
