He said it does everything it is supposed to do. It works very nice, it seems to be a very high quality, and it has already been an extremely helpful item for him! He was sad that it is made in China, but he said the quality seems to still be great for OTC. He does think that for the $100+ price, it should come in a case to keep it safe as it is a bit delicate to be loose in a toolbox drawer. I'll be looking online to see if I can find him something to put it in.
