This gets into tight spaces on the car where other benders won't fit.

Nope, its junk
Doesn't bend to the advertised degrees. It's a few degrees short of 90. Bends ok on smaller tube sizes, but it looks like it's bending on the larger sizes

Useless - not as advertised.
Broke part way through my first attempt with 5/16" steel tubing (also supplied by Eastwood). Pinched my middle finger when it broke....... will be returning and recommending Eastwood pull this product as is it NOT fit for purpose.

Waste of your time and money
Mine broke on the first bend attempting to bend 5/16” fuel line. The line was not stainless. The tool may work on 3/16” or 1/4” but no way for 5/16” and 3/8”. Frustrating waste of time.

Questions & Answers
Can you straighten the line with this
This tool isn't designed to straighten line. We do have a couple options for line straightening though.

What is the radius of the bend? Looks like it may be a different radius for different tubing diameters. Asking specifically for 1/4 inch.
The maximum bend would be 90 degrees on 3/16 and 1/4, on 5/16 and 3/8 it will be 45 degrees. As for the radius this tool is not designed for that.

Where this tool made...foreign, what country???
This tool is made over seas on our lines in China and comes with a 1-year warranty.

Do the two bend guides roll/turn, or are they static (i.e. fixed, don't spin ) ? The tubing bender I use drags across tubing causing kinks.
The two outside guides do roll to prevent kinks.
