Does the job
Very heavy duty and works well. Very easy to use and value for the money is solid. I want to highlight how well the head swivels and can be adjusted to the location you need. As well, the quick adjustment for handle length works incredibly well, is very heavy duty, and does not flex at all during use. It did the job and was quite a bit more heavy duty than expected.

It bends stuff
Bought this to bend some cattle panels into tomato towers. The tool is very sturdy and seems really well made. The head locks in position positively and doesn't wobble around when locked. The handle extends with a push button and also locks without any movement. It works very well for bending 4 gage galvanized steel wire. The adjustable head made it easy for me to get the bends correct and the extendable handle gave plenty of leverage. Don't know how well it works on rebar, but if you need to bend something, this will do it.

Mostly works
Works pretty good if you have a vise. Rebar on right side of pic is without vice. On the other side is with. I have to do a ton so it is taking quite a bit of muscle to bend each one that much. But technically it works. I recommend for smaller projects.

Flexible for tight areas on existing bars
Good and sturdy for number 3 and number 4 bar only

It's ok, but .....
The tool works - but it's not easy to bend rebar at a specific point with it, and still requires muscle to do soWhen bending a full 20' bar, it bends close enough to where I wanted it bent, but for a short bar, it's easier to use a pipe and vise - Pipe and vice also allows a tighter bend then this tool does.

Great Tool to bend rebar.
It works very well... Angle of work and also leverage can be adjusted. Neat looking. You will need 2 of these. One to hold the job in position and the other to actually bend. You also use a vice improvise a sturdy table with stubs of steel to instead of the 2nd piece. But its easier & cheaper to get the 2nd one.
