Good value. Good wrench.
I bought this 2 years ago I still use it everyday with no problems. I do industrial ammonia.

Worked fine after minor modification
For a residential Rheem system, the liquid valve is recessed enough that the fitting included with this service wrench won't engage the valve port due to the larger 5/16 hex portion contacting the body of the valve. No big deal, but had to grind the 5/16 size down enough to clear the valve opening.

Just what I needed!
Couldn’t have replaced my fan motor in my Carrier system without this tool. Worth it to have to keep from messing up that one bolt!

MGB rear brake adjustment tool
Exactly the tool I needed to adjust the rear brakes on my 77 MGB. 1/4 square ⬛ ratchet wrench

Broke the teeth on it after a few months
They're nice but always kept an Allen wrench back up in my bag bc some king valves are tight and these can only handle so much torque.
