Harbor Freight - Gems and Junk

I keep their solar battery charger on my car trailer winch battery. The battery is always ready to go when I need it. Everytime I've had to replace the unit, it's been my fault.(.I dropped sommething on it, etc) Even then most of the time, the extended warranty replaced it. Same with floor jacks and engine hoist rams. I always get the extra warranty. I have their high power air impact which for $79 has worked as well as the $300 Snap On that I used to have. Also, I really swear by their 110 lb pressure sandblaster, although I modified it and bought a tungsten nozzle instead of the cheap ceramics that it came with. The $10 die grinders and air chisels just can't be beat.
I bought the very cheap ($15) air powered ac vacuum pump which did draw down my ac system twice for an hour each time. It still works, but it has started making a "death rattle". I've also got their AC gauges.
