Accurate and easy to use. Elimates guesswork. The only problem was with the packaging and shipping. My checker arrived with the smallest nut checker bent over at about a ten degree angle. This doesn’t seem to affect the use but I am concerned that if I try to straighten the threaded rod it might snap.
