I have a lot of garden equipment and some vehicles that seem to need air more often and I have reduced the price of compressor equipment. Over the years I have had to replace most of these fittings such as quick disconnects, swivels and now air chucks. My angular double head literally fell apart in my hands a few days ago and the backup leaked to me. I recently bought a straight chuck but it didn't turn off so that was enough and I went with this one. For the price I don't think I could do better and the straight end makes it a lot easier to access some of the rims and it matches the stems well. I'm done with the cheap Chinese stuff I get from HF so it was a pass/fail for me and it works as it should so no complaints.
