This product is terrible. The ratchet mechanism also does not function satisfactorily Since the jaw that holds the upper nut is arbitrarily opened during use, it does not function as a wrench. It is in the form of a wrench, but this is not a tool.
I was interested in how to make ratchet function and purchased it. It was a structure of "scales from the eyes" that can make a nod and that way. Usability is not very good, but since there is no other monkey with ratchet function attached, it is handy as it is.
I wanted a short handle so I used it in a narrow place of the car. It seemed interesting, so I purchased but there was no stopper for not ratcheting, so it was not useful because it can not be used except for one way use. I think that the normal monkey was better.
