I bought a cheap set of impact sockets from Super Cheap Auto about 25 years ago and they have been great, I use them a couple of times a week on average often with long cheater bars as well as the impact drivers, they have been great, indestructible and I am proud to say I have not lost one of them out of that set. I recently bought a 3/4 drive set that goes up to 65mm but have yet to use them, I am thinking for some of the big nuts on my earthmoving equiptment like the piston nuts on the rods of hydraulic cylinders. I have an air impact driver for the 3/4, I woulde love a Millwauke but my budget doesn't extend to that yet. When you have the right tools it makes a big difference.
