For four dollars, you can't really expect that much from a screwdriver (even a ceramic one) and indeed, the screwdriver handle's build quality is by no means excellent, but the ceramic tip seems to be of good quality, which is really the only part that matters. All in all, an essential tool for anyone working with electronics that have small knobs that needing adjusting while powered up.

Put off buying one of these for years as I was just "careful" with a normal metal screwdriver to adjust pots on stepper motors... Till I wasn't... and killed my Arduino in the process. Bought two of these when I bought my replacement MEGA2560. Very happy with it so far.

I had lost my previous ceramic screwdriver, so finding a a non-chinese supplier, with quick delivery was fantastic. Now I can adjust my LCD screens and stepper drivers with piece of mind.
