I didn't actually buy this tool, a friend of mine gave it to me. I was happy, he said he had two. I took it into the shop and what a disappointment. It is sad that companies get away with selling this low quality merchandise on the market. But sadder still, my beloved Amazon, in whom I have become a firm supporter over ten years SELLS the stuff. Is there nobody who examines this merchandise before they begin to sell it?  You would think that there would be quality assurance departments staffed with people knowledgeable in their fields with certain kinds of tools. Or send ten out to carefully selected "experts" who would try them, evaluate them, and send them back to Amazon with a critique. I have to admit, I'm scared of what I see happening with Amazon over the last few years. Walk away from this one.
