I've used it for a couple weeks so far and so far so good! For the money, it's a great value. If I can get a couple years + out of it, I'll be very satisfied. I've used it to cut/repair the frame of a TJ Jeep Wrangler and it cuts through pretty good. The thickest metal I've tested it on is about 1/4" steel and it did a pretty decent cut. If you can't afford the $$ of the big named brands then this is the way to go.
