"I use Timer Caps for my medications, and the batteries in them were starting to die. Fortunately, the replacement batteries are cheap, but the screws holding them in are microscopic. I tried to make do with a pocket knife, but even though it worked, it took forever -- and I was afraid I'd strip the screw heads and ruin them. So off to Amazon I went, in search of the world's tiniest phillips head screwdriver.I didn't want to spend a ton of money on a tool I'd only use for about 5 minutes a year, and there were lots to choose from. But many of them appeared to be from the same questionable manufacturer, just packaged under different unfamiliar brand names. And the reviews weren't good. So I followed some of the reviewers' comments and landed on this little set.The price is right, and the quality is wonderful. The set included the exact size I needed, and they're easy to grip and use. Plus, they're magnetic, so that teensy little screw didn't get away from me. And unlike in the reviews on so many other similarly-priced tiny screwdrivers, this one didn't twist or warp or strip during use. Now they're packed away in my little tool bag, ready for the next time I need to remove a screw the size of an atom."

I just needed a cheap set in order to take apart an old laptop and these screwdrivers worked. They seem cheap so I'm not sure how well they'd hold up long term but they sufficed for my purposes. If it was something newer I had to take apart I'd have opted for a higher quality set, though. They included in a clip thing with my order as a gift.dave kramer

These were great for removing sticky screws from a FitBit. I had an old set of screwdrivers but they had skinny handles with no torque. These worked great and did the trick -- at a great price.mitchell rose

I bought this for a project that I needed one of the drivers for. I didn’t want to spend a lot of money as these will be spending their time packed away and probably not used except once in a great while. The magnets work and the spinning top made using them easier. The plastic and fit and finish is fine for the occasional use. They don’t come with a storage case. I just keep them in the cardboard box they arrived in.What Customers Talk About
