  • Works great
Great

  • Three outta four ain't bad, I guess..
Will not fit a2l and r22 caps. Both 410 sides work fine and the Schrader core tool works kinda. You gotta be perfecly in line or you'll blast your hand with refrigerant. In my opinion go up a little bit up in price so you don't have to modify it to work like I did.

  • Key shaped bits too big to fit
Doesn’t fit small or large key-shaped locking caps, too big. You gotta use pliers to force it in and then pry it out again. Garage
