I bought a batch of these, size small for my Grand Slam.
I've used two of them and, so far, I'm really impressed. The fit is perfect. They last for many cooking sessions and the baked on black stuff usually pops right off if I'm not yet ready to use a new one. They take the hassle out of foiling or scrapping the grease tray.
They may seem expensive, but it's worth it to me. Cooking on my GS is one of my few hobbies nowadays, and the cost seems minimal compared to typical hobbies such as golf, fishing, etc.
