Probably a useful collection. Only really used the cleaning spray. The shavings seemed a bit coarse to use for beeding and I had bought some Aubiose which my girls prefers because it is soft and light. I also use the aubiose in their litter trays. DE - waiting for signs of any nasties before using it and none yet. Grit - well I read on the Omlet organic feed pack that its already included in the mixture so no need, and mine free range most days so have access to gritty soil. Would I buy it again? No.
