No only some. A regular KM is awesome too but i just love the ice chamber feature.

the KM's with the ice chamber cost a little more but honestly i think its worth it but if you dont want to spend a little extra a normal KM is amazing too. Plus they come with nice hoses that sell for about $20 each =)
Also check out your local hookah shops cause sometimes they will have KM's for cheap. Like the 38" KM ice in my pic below i got at a local shop in tempe, az for $95
