I bought this to replace my Craftsman plastic measuring tool which finally broke after 40 years of accidental use. The tool is made of hardened stainless steel and runs smoothly with little effort. I likes the analog meter is well labeled with fractions on the white outer dial and decimals on the green inner dial.mine arrived with only one loop.I had to cut off part of a large paper clip to put it in another loop but that wasn't reason enough to downgrade the tool from 5 stars. Nothing more to add except that it is a heavy duty tool that should work for years. Too wide to fit drilled holes. m over 1/4 in. My old handyman had a probe, a Steel rod that fit in a hole only 1/16" in diameter. Not a deal breaker, just a limitation of what a 5-St erne rating should be.
