I've never seen these before so thought I'd give one a try:
Its actually really good, I've had to do a lot of cutting of thin sheet steel (garage doors) and it seems to run cooler than standard metal blades - doesn't burn the paint, fewer sparks and the main advantage is that it doesn't wear down so you can do deeper cuts in corners and recessed areas without running out of blade. It's also gone through some 8mm steel plate with no problems and still seems barely worn after cutting what I would normally expect to use 10-12 blades for.
