I was replacing every hard line on my F100. After an day of botched flares with my old hand held tool, I decided I would give this Eastwood Tool a try. I was a little shy of the price, but decided that if it worked it would pay for itself on the first job. Boy did it work!!! I cut a few short pieces of tubing and found that it was IMPOSSIBLE to make a BAD flare. I bent, flared and installed every tube on my F100. Then bled the brakes! Not one leak!!! This is one buying decision I have not regretted. Thanks for a great tool Eastwood!
