The first roller I recieved was damaged in transit but the seller replaced it immediately.As for the slip roller, it does roll 16 gauge mild steel, slowly with many passes. It's really better suited for thinner material but it will work at the max rated capacity.Fit and finish is what you'd expect at this price point. The casings are rough and the paint is terrible. The bushings for the rollers clunk around in the casting.But I still give it 5 stars because this is what you should expect at this price. The Eastwood unit is virtually identical, made in China like this one, and twice the cost. I'd be extremely disappointed if i paid $500 for this quality.
