This wrench is perfectly adequate for occasional use, and the price is hard to beat. I only need the 30mm size for the crankshaft pulley nut on my Porsche 356 coupe when setting the timing or removing the pulley, which is not very often. The same type/size of wrench at Lowe's cost 4 times this amount and was not significantly better.
