I bought the key especially for my new faucet and was the mother (SW32) not put, because the key is too small a lot. The description and the product tags on Schlüsel have made a clamping range of 9-32mm. I then hurried along with the angle grinder and the jaws slightly enlarged. Otherwise, the key is well made and the forged jaws are also hard. The telescope and the gags are thermocycling massively. Maybe I was just unlucky and got a bad copy.
