I've purchased my fair share of their stuff...pretty much when it's on sale. You have to watch their pricing and I just wait until it goes on sale. As a frequent buyer club member I've saved a TON of money on their sales and they pretty much take care of me when I do get a junk piece. I have four 4.5 in. grinders from 4 different sources and they all work about the same, including one Milwaukee. I have a wire wheel, cut-off, grinder disc and flap wheel for finishing. That way I don't have to switch stuff out constantly! I just end up winding up a BUNCH of cords after a project! IF I had more wall space in my shop I'd just make a hanger for the 4 of them on the wall by my welders and leave them out.
Anybody tried their 120 and 240 volt spot welders? They get decent reviews and one guy said it was the same as the $600 Miller? The Chinese are VERY good at knocking stuff of...so I reckon they could've copied a better product for less?
