A few years ago I bought a long handled flex head 1/2" Armstrong for about $70. It took my technicians about 3 weeks to break the cheap pop metal direction lever. We got about 1-1/2 years use out of it after that using a 1/8" screwdriver to change directions. Then the head broke clean in half, not even at the flex joint.
We have used Craftsman's cheap Microtooth/Microtork ratchets for 8 years and have never broken one yet. Out of 8 we have had 2 that were lost/stolen and zero breakages. They just need to be cleaned, lubed and have part of the direction disk filed for clearance about once a year.
So I guess I would say that Armstrongs don't hold up to the abuse in my shop but cheap Craftsmans do
