A good product, have tried other substrates and have gone back to crestie it suits my needs.
My last few rats/mice orders have been well packaged & fast delivery, Better price than swell reptiles.
I rang the shop and explained that my reptile had been without uv for a week as I was struggling to get a replacement bulb. They told me this bulb had been discontinued and sent me a different setup which arrived very speedily.
I was impressed with their customer service.
