Buff the coating off and it's amazing.
This little guy is almost perfect. My only minor gripe is the black coating is too grippy. I used a very light abrasive soft wheel on a drill to buff the coating off. It works brilliantly after that. The trick is to squeeze a little, let off a little, spin it a little, squeeze again - a little more - and keep working it around like that until it's completely expanded. Otherwise, you'll either split your copper, or it'll just be egged and you'll end up having to work it around anyway.

Best value for moneyYou should know the technique, though.

Decent
Works but already has trouble folding after 3 uses on 3/4" ACR copper

Works good as a backup expander
Not bad for the price point. Takes a few minutes to get it to where you’d want it, and you need to be careful to not over do it, because it is easy to crack the copper with this tool. I wouldn’t recommend it as a primary expander, but it is good as a backup or for tight spots. If you’re looking for an expander you know you’re going to use a lot, just spend the money on a Navac or Hilmor expanding gun.
