Very good product. Malco makes quality tools. Seller shipping is extremely fast. Wasn't supposed to arrive until Monday and it arrived Thursday. 3 days early. Very impressed!
I used to cut 26 and 29 ga metal with fabricated ribs. Works great on the flat metal- cuts like a knife Thru butter. However it doesn't do so well with raised metal. It works ok with the 29 ga with some difficulty however it sucked on the 26 ga- it will not cut over or under the 3/4 inch ribs at all.
