Bought 2 at once recently and the first one I used cracked. Not sure if it was maybe a quick change of temperature or what. I bought one of these before buying these 2 and it broke as well but that was my fault for using cold water and temperature change. Not sure what happened with this last one. I have 1 more left. Not that bad because of the really good price tho. Hopefully my next one lasts longer. An aluminum version would be a game changer. Very fast shipping and great service from Hookah lab. No complaints from them.
