I'll put it to you like this, if I were to lose mine or ruin it in any way I would not think twice before paying another $40 for it.
And yes, I do realize it's ONLY a screwdriver. But it is the Holy Grail of Screwdrivers. Monty Python can't touch this.
I concur.
For commercial, industrial, I find it invaluable.
I bought separately assorted bits that include Philips 3, Square 3, various Torx sizes and Hex sizes.
If it looks like I'm going to be using something that isn't in the Wera, I swap it out. I almost never use the flatheads (and I carry a separate flathead usually) so I've taken them out completely.
Having the appropriate sized bit is important since I use the shaft in my impact, be way too easy to cam out screws and bolts otherwise.
