If I could give these 4.5 stars, I would, but they're not quite perfect. Definitely along the best I've owned, though. I love the knurled base, makes it much easier to turn nuts and bolts using my fingers. The flats inside the sockets only go down about twice the thickness of most nuts and bolt heads, so there's no chance of losing a nut or bolt all the way at the bottom of the socket. The flats are also machined to grab nuts and bolts by their flat sides rather than their corners, which helps prevent rounding. The walls are nice and stiff, but still thin enough to fit in tight spaces. The larger sockets (9mm) are stepped at the base to make it easier to pull them off ratchets. I love that the size stamping is on 2 sides of each socket, making it easier to spot the one I'm looking for. And they're actually stamped, not 34;laser etched34; or printed. I've got many so-called 34;laser-etched34; sockets that have had the size marking rub off. The selection of sizes is perfect and doesn't skip any size from 4mm to 15mm. The storage rail is sturdy plastic, and the clips are easily replaceable. So why not a perfect 5 stars? The size stamping is kinda faint and hard to read. I've got some old budget Mastercraft sockets that I bought at Canadian Tire 2 decades ago with much deeper and clearer size stampings. Heck, even the Gearwrench name on each socket is stamped more clearly than the size. That seems like an odd thing to cheap out on. Also, clips on the storage rail can easily slide off on their own at one end. There's a little plastic retainer that's supposed to prevent that, but it's molded too far out to actually do its job, so if you hold the rail by the wrong end, a bunch of sockets can slide right off and fall on the floor. Ask me how I know that... Again, that seems like an odd thing to get wrong when almost everything else about these sockets is so awesome. For the price, nothing beats these sockets. The features are useful and well thought-out. I could overlook the poor placement of the clip retainer on the storage rail, but it seems to me the size stamping could be improved at absolutely zero cost. That would make these a perfect 5 stars. As it is, I highly recommend them.
