This tool works well and is priced well.

Great tool
Super handy to have for more than just HVAC work. Most bits will fit in the quarter inch drive and now you’ve got a right angle hand driver.

It strong enough to handle any construction jobs
I love the stability of the wrench and how it fit in my hand when I use it

Had to modify the combo hex bit
The wrenches aren’t the best quality, but they work OK and are reasonable for the price. They would certainly be fine for occasional use.The hex bits are a hard steel and should hold shape without rounding off. However, I did encounter a problem. Both combo hex bits are the same and are stepped to provide two different hex sizes on each bit. The added length, due to the step, can create a problem. They’re too long to squeeze between the suction line valve and the AC housing on some AC units. They’re unusable, as delivered. Liquid line valves are smaller and have more clearance. The combo bits work OK for those. Also, the smaller hex section sticks out and prevents the larger hex section from fully seating into some suction line valves. You run the risk of stripping out the valve.I solved the problem by using an angle grinder to cut off the smaller hex portion of one of the combo bits. It’s now a single, large size hex bit. The modified bit is short enough to fit in the suction line valve and it fully seats. I use the remaining un-modified bit for the smaller liquid line valves.

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.
