For the money its a very useful tool, able to bend thin wall tubing with very minor obstacles. I was satisfied with the results of bender with only a few minor issues. The plates that hold the tube on the back side of the inner radius die needs a good chamfer. It would leave a little crease on the tube from the pressure of bending around the radius. After giving that a proper radius there were hardly any witness marks.I was able to bend 1" tubing with only moderate effort, would definitely encourage a strong rigid table to mount to though. Size changes were fairly easy, taking only a minute or two to completely go from size to size. Its a decent bender for small projects and at a price point that is hard to argue with.
