I would never, ever, consider buying a torque wrench from them.
Back to the topic, buy one of those adapters shown above for a couple bucks and you can use any compressor.
The big issue with HF for me, as a hobbyist user, is the low quality which makes using them unpleasant. Slop in joints, rough cut threads which don't spin well, crap bushing material giving rough feel, grips that spin on the handle...stuff like that. Just cheap, junk construction and materials that feels and works like cheap junk. I hate it, but the cost tradeoff for my small, occasional projects and periodic needs keeps me going back, because I'm not financially well-endowed. I do get Snap-On tools through an auto tech buddy, and for some basic tools which I always use, like the ratcheting bit driver, they're a real pleasure to have and use. I buy HF tools knowing using them is going to be frustrating.
