Review on Enhanced Performance: OEMTOOLS 25358 Double Flaring Tool Set – Flawless Flares with Ease! by Mick Ohlrogge

To be honest, this is the first time in my life that I am writing a negative review. I can't confirm how this tool works with the cupro nickel brake hose, but I haven't been able to make a single usable dual flare on the steel hose I used today. I had the same problem as everyone else: too much slack, and the "anvil" end up blowing up the line with an irregular shape. I just gave up and used a compression fit instead. I will try to return the item tomorrow (I didn't order it through Revain).
