Par4QC I have never had a failure until Bramptons.. so that ought to carry a little weight too. Thankfully, it wasn’t catastrophic, the head just twisted on the adapter and I felt it the minute I hit it. I have used several bottles of Bramptons with no issues as well, but same process, yielded a poor result last time.
If a product has a reputation, and you have never experienced it, but then you do, your opinion changes. The Ford/Chevy debate will live forever, both sides will say the other sucks. I always figured it was user error.. not buying that now. I have broken a shit load of shafts off at the hosel, had steel shafts bend at the hosel, never had the epoxy fail, so that should say something too.
