I've got stubbys and full length in metric and SAE. Note: I don't care for the ones that have a "switch", like a socket wrench handle does. They can bind up. Instead, I have the ones that you flip over to "reverse" direction. No problems with those.
Ya, thats true about the ones without the switch being more reliable but I need the angled head to be able to be used either way depending on the obstacles to the nut. That requires the switch because the thing might only fit one way so you have to make it do what it needs to do (switch)
