So, I tried reptichip today for the first time, set up a bigger cage for Amora today and had the chance to get a brick when I bought her last week. So far, im liking it better than my old standby eco earth, it seems to hold moisture longer and doesn't stick to the snake. My brick wasn't dusty at all, and I used a screwdriver to flake away the amount I needed without soaking the whole brick. I may try reptile prime eventually if I can get it locally or at the Rexpo show in april. Seems the best way to judge these things is to try them out yourself.
