I'm a little indifferent to this wrench. It is very suitable for tightening and loosening nuts. But once the nuts are loose, this tool is far from ideal for quickly loosening them. I'm pretty used to using a 4-point wrench and being able to turn the cross in the palm of my hand to quickly loosen nuts. This wrench takes a few turns to loosen the nut and then has to be unscrewed by hand. The shape and size of a wrench is great for loosening or tightening nuts, but it doesn't help loosen them effectively. However, the wrench is of good quality, feels good and works very well. The telescoping function is really good and doesn't feel flimsy even when extended. You can actually crank it hard without much effort. The length is great for getting good leverage on the nut. The kit includes two reversible sockets for a total of four different sizes of sockets. They fit both SAE and metric sizes, providing a kind of "close enough" match between specific measurements. I've had no trouble installing or removing SAE nuts and metric nuts. There's also a vinyl tool carry case so you can toss everything in a tool box or trunk and keep your sockets and wrenches together. Wrench for the crossbars for quick unscrewing only.
