Very easy to install into the grip and very comfortable to hold. I had it fitted into my Spyder Rocking Trigger Frame and there wasn't any problems.
At first impression, I thought the product made the frame grip too wide and thick, but it's actually at the right size. The material for the grip comprise of mostly rubber, which makes the marker more comfortable to handle compared to the stock plastic cover. During play, the grip might not be as sticky as one might expect because of the paint that splatter on the grip. A good clean wipe would solve that issue.
I would recommend this grip as an alternative to any other grip, but I'm not sure how much more different it'll be with Dye's sticky grips. Otherwise, it's an excellent product.
