Completely UNACCEPTABLE. It cuts at a 48° angle instead of 45°... as a result, it doesn't make the correct angle and you end up wasting iron! It struggles to cut 30x60 iron, it heats up the metal, and the motor gets hot after one cut!!! It seems like its rotations are much lower than its specifications. It says 2900 watts on the box, but it's probably 900! A complete waste of money. I bought it specifically for the angles, but it cuts them at the wrong degrees and, of course, the clamp "pushes" the metal instead of holding it. Overall, a very poor construction and a regretful purchase.

UPDATE:
After just one month and 20 cuts, it BURNED OUT!!!!!! The service repaired it for me, but what can I do? I did most of the work with an 850w handheld saw... Now it collects dust in the box...
