Worked poorly, then broke
I tried about 30 times to make a good flare on 3/8 copper nickel, wasted quite a bit of tubing and several hours. Flares kept coming out with the bubble collapsed or with creases in the flare. I couldn't figure it out. Finally, the bubble flaring anvil snapped in half: it had a crack in it from the start, and wasn't holding its internal conical shape when pressed into the tubing.

Had to go to the auto parts store to get a new tool to finish the job- the new tool worked perfectly on the first try.

Gets 2 stars, because the bending pliers and cutter worked fine, though they are definitely of cheap construction.
