When I bought my first one (Thats the one in the picture), I opted for the smaller kind, thinking I was prolly not going to be using it much. Boooy, was I wrong. lol. I’ve found that it best to always invest in a bigger one, seeing how those seem to work better for the shiisha smoking! After having bought one, somehow its opened a new way of socializing, as my buddies and I have the deepest most chill conversations while puffing away! lol.
