Did you put the Costar stabiliser inserts in with the correct orientation?
I don't have costar stabilizers. Ducky Shine II is what I'm using this on.
And yes, finally. Someone else noticed that the keys are warped? The stems aren't pointed exactly in the same direction. Exactly as in maybe they are maybe a couple of minutes of angle off (1 minute is 1/60 of a degree).
I don't know about ripping off my stabs...lol. It seemed to work a little better on my friends Leopold, but regardless, still didn't feel as smooth.
Also, I noticed that when they are laid on a purely flat surface they don't sit that way...
A little disappointed in the QC of this product.
