Bought to replace a cheap other brand that was lame and inadequate. I bought a diamond blade, cut the tile with ease. I was a little worried that 7 amps wouldn't be enough, but the power is enough. I then used it to shorten the chrome bumper and that worked without any problems. All the work I have done has not caused any problems. My only complaint is the security. Tends to have difficulty turning. Otherwise this thing rocks! Highly recommended.
