i don't buy much a hf but once and a while i get suckered in. i do get the cut off air wheels, gloves, and some other consumables there with no problems. i did try a air scraper for $10 a while back, wouldn't even move. took it back in exchanged it, same thing. tried one for the 3rd time and still the same- i really need this for a single project. i didn't even care if it worked after that. finally looked on their website and tons of people were having the same problem. one person they took theirs apart and reworked it and it worked after that. they must have had one heck of a bad run on those. i just thought it was funny every comment/review on their own site said this scraper was junk!
