Review on Wera 05118066001 Screwdriver Electronic Applications by Guillo Tilden

The hex on this sprocket should technically be better except the sprocket is tapered rather than the right size. This means no screws are left at the end. Also, it means you don't have a form-fitting fit so if you put a cap on at all, even a very small one, you'll slip off due to the taper at the end. This causes the screw and/or the head of the screwdriver to wear out and otherwise become damaged itself. That's a bad screwdriver. Good reviews are weird and I wouldn't trust them. It could be a good driver if they paid attention to the design, but they don't. I've had mine for a long time and still use it even though it sucks, it's what I travel with. It wore out after a year or so with very infrequent use so it's not even durable.
