I've had OTC stuff break also. All depends on the amount of pressure being applied. Heat is your friend on stuck components! You could buy almost 3 sets for the price of 1 OTC. Thing is, they probably come out of the same over seas factory. One goes down a different line for more refinement while the other just gets boxed up for shipment. Your money your choice. Just wanted to show there are other options for the same type of tools for the job at hand. Yes, at HF, you have to be careful on some of the stuff. I'll get the lower end wrenches and cut, bend and weld back together different sizes to make a wrench for the job at hand. Really handy for putting together tools for a toolbox on the tractor. Like a 14mm open with a 10mm box on the other end. Cuts down on the amount of tools being carried where space is limited!
