I've bought about two of these sets. This is a great set of bits and screws, it has almost everything you could possibly need in a screwdriver set! I use them to work with computers and other small electronics, it opens everything from cell phones to Xbox, it doesn't come with any proprietary bits, so you might have to shop around for them, but they should still fit in the screwdriver! The reason I like this one more than any other is that it fits almost any racquet, it holds the racquet in place with the collar, you twist and pull the collar around the racquet and thereby secure it which means that, if i have a bat in the wrong shape or size, it should fit, if it fits in the collar and is not too small, it should fit! Now, this is my favorite electronics screwdriver set, but it has its drawbacks. First, the screwdriver is a bit small, I have big hands, so it's a bit awkward to grip. Second, and this is the problem, the kit "extension" is *required* to be used at all times. Otherwise the bit will slip and fall out if you put even the slightest pressure on it. It wasn't immediately clear to me, other than that it works great! I would recommend this set if you just need a general purpose screwdriver set that will fix just about anything around your house! I wouldn't use them for cars or industrial stuff but they will last a few years before being replaced, that's for sure!
