I have briefly (for a week) used reptile prime. Used in it an aquarium at that. Easy to keep humidity with that stuff. Didn’t feed on it since it was only a week. But everything I have been told is it will be fine, and it seems as if it will. Their rather fine pieces so even if the snake swallows a piece it should be alright. Spot cleaning was simple, my Suriname pooped/peed while she was on it. Great absorbtion and I didn’t notice any smell. I just ordered a bag about 2 hours ago. I only switched her off it because I came to realize she had mites. So she’s on paper towel for now, and for probably at least another month, assuming I’m correct in these pesky insects are gone, which they seem to be.
