In general, I just love these pens. I particularly like that they are the right thickness, (when heated) pliable and easy to apply, the edges don't peel at all after a week of use, and most importantly, they definitely help me stay in control during fights and Game sessions (sometimes FPS) which is the only reason I bought them. Overall, I am very happy with my purchase price and the quality of the product and I was happy to support this backyard/American company.
