most of us don't use those hides because they do not provide the security that beeps need (cave-like with only one opening) as well as being hard to keep clean.
i started out using Exo-Terra hides like these but the uneven surface and little grooves made them a pain to clean, however i liked their look and the weight they had to them.
now i just use RBI hides; they're cheap and easy to clean. they're not prettiest hides around, but they're practical. only thing i can say i don't like is how light they are. i still have my old Exo-Terra ones just in case i need them.
