At first glance, I have to say one thing, that you pay... you get. The nuts, half of them have a slit inside to fit the wrench, and the other half don't. Half of the ones with a slit don't even fit. So basically, we have 1/4 of this big set of nuts that "work properly". The wrenches themselves were not bad. Of course, for me, because I only need them for occasional use, they are fine, but for someone who will use them every day, they might consider getting a better brand.
