Wrench seems to be of good quality and grips nuts with enough force to tighten or to solve. However, the part of the wrench that opens/closes for different size nuts is wide. Consequently, you need enough clearance around the nut to be able to turn the key. To make sure you understand the gap, imagine laying the nut on a table, applying a wrench to tighten it, and then turning the nut with the wrench - you need enough horizontal space around the nut, to turn. This is due to the width of the shoulder of the key. Unfortunately I don't have enough space under the sink so I can't use this key. When I was buying wrenches, it never crossed my mind if there was enough clearance. I will not forget this lesson.
