We bought one for our GBLE and while the ball has no clearance issues going under it and it DOES help reduce the crazy balls flying around, I found the ball would fly off the ramp to the left, smacking the back and sides of the cabinet instead of going around to the right like it was supposed to. The protector lasted about 10 games - took it off and no more balls flying off the left side.
Has this been a common complaint and has the "new" revision addressed it?
