Total crap. Center pin broke off die for 3/16ths line on second flare. Replaced with a unit that came with a lifetime warrentee for $13 more & did the rest of the brake job no problem. Might get a couple of bucks back in a yard sale - waste of money, garbage.
Purchased one, flares were off-center. Purchased a second one (hoping it was a one off issue), flares were off-center and the flare was lob sided. Tried it multiple ways, multiple depths, with and without a vice, no success. When to a tool rental place to try their unit (in case it was my technique causing the issue) and the very first attempt resulted in a good flare. The machining on this tool is inaccurate (especially the bevels) resulting in blind luck needed to get a usable flare. Returned both units as poor quality and defective.
