I bought this tool from another seller. The one I have doesn't deserve the previous negative review. Works well. The manufactured flashlights are of high quality. Suitable for both mild steel and Nicopp/Cunifer lines. Probably not suitable for stainless steel pipes. The block needs to be tight - get out the ratchet and hexes as a hex or hand wrench will not help. If you are threading a large sleeve, you can make a cross thread. Make sure the sleeve rotates fully and is square to the block. Otherwise just follow the instructions. Some brake fluid for lubrication helps.
