Very good product...
This is a very well made wrench. The tolerance is tight enough that you have to get it right over the nut so it will slide on. The only negative I can come up with is inherent to box-end wrenches. i.e.: the router bit needs to be smaller than the inside of the wrench. But that's why I have an open-end wrench as well. However on a daily basis, I will be reaching for this wrench when possible.
