Does the job but you need to fiddle with it.
Rolled a pair or 4 1/2 ID rings using 1x1/8 A36. Simple enough! I used a file to cut a nick in the adjuster knob so I could count turns and get back to a previous point of adjustment. Very helpful. If you want to make multiple rings cut multiple pieces of stock and run them all through, one pass each before you adjust the knob. This is a low cost tool so don’t expect too much. If you are working around your house and need a part now and then it will do fine. If you are planning on using this tool to make money with it it will probably drive you nuts! I recommend it for the homeowner.

Decent inexpensive roller.
Works well on 1"x 1/8" flat, though it is a bit difficult to adjust to the exact diameter you're shooting for. I mounted it to a post for clearance of the stock.

Works great. Purchase with confidence.
Heavy-duty, functions well. I needed to radius sq. tubing for my driveway wall this unit made short work of my need. I am not a metal worker I just had it home do-it-yourself need. This fit the bill perfectly. Purchase with confidence.

Works ok but the knurling will leave marks.
It works ok, not bad for the price but do be aware that the knurling on the wheels will transfer to the material you are rolling, espaecially if you are rolling aluminum round stock.

Came way to greased up.
Came way to greased up. Quality isn't all there for a $100 but all and all I would buy again

Handle comes in two pieces.
Item is as described, well built, except handle is in two pieces, probably for packaging purposes, but a little welding will fix that! Delivery was prompt. Great tool for bending and making circles with round and flat stock for x-mas decorations.

De mucha utilidad
Lastima que no pude regresarla pues al otro día de la compra le bajaron 2000 pesos ( ojo amazon con las garantías )

Great bender
I received the bender yesterday and got it mounted to my welding table. Within an hour of getting it I was trying it out. The bender appears to be well built. It bends the curves easily, just don't rush it as I'm positive you will link the material if you do. You are pretty much on your own to figure out how to use this properly as the are NO instructions on how to properly use the bender, only setup instructions are included. I'm hoping Google and YouTube will be a help so I don't waste material. I spent a couple of hours playing with it with scrap peices and the curves were good and got better as I kept playing. Having never done stuff like this before I was impressed with my results. I would recommend both the seller and the bender to my friends.

Works great!
Works great! It would be nice if the rollers could fit 5/16” or 8 mm diameter material.

Works,,,, but
Works fine but be aware that the 1” is as wide as this can handle, and as for thickness, less than 1/8”. Other than the limitations on this roller, it’s well made and does (just) what is advertised. Would recommend it on its quality built.
