This refrigeration wrench is the best of it's kind I have ever used. I have had several brands of these wreches, none of which could compare to this one.Yellow Jacket, and Gearwrench are some of the other brand refrigeration wrenches I have used in addition to various cheap brands from the supply house. Most of those ones are actually quite uncomfortable to use and end up cramping your hands. They also have the problem of being too fat in the handle.This one, however is perfectly sized lengthwise, and the width of the handle is great. It really is a comfortable tool to use and will not bother your hand. There are some days that I do not even use this at all, but when I need it I'm glad that I have this one. It really is a great, quality specialty tool that if taken care of should last a long time. But honestly, should you expect anything different from Klein hand tools? I think not, at least with my history of using them.
