A couple of years ago I bought a jumper box with an air compressor built in. After charging it according to instructions, I decided to see how well the air compressor part worked. As soon as I started it, it made an ugly rattling noise and started to smoke!
A 4 wheel engine stand I bought had the main post welded backwards, so the engine was slightly tilted forward rather than back. But I didn't realize it till I had used it for a while and double-checked other engine stands.
They sell 4-socket tire irons, which are the same ones found in most other stores. Theirs is the least expensive so that's where I went (with coupon) when the last one broke in the shank after several years of tightening the lugs on my race car by hand! (I swap rear tires and adjust the brakes after every weekend of racing.)
