The size, durability, the amount of volume you need to milk a bong rip on this piece is perfect. You do not ever have any minor inconveniences other bongs in the past have given me. No resin collects on lips or close to the mouthpiece. Super easy to clean and is the perfect travel size and it is not so big that it stands out. Had is as my "teenage hideaway piece" and nothing has ever come close to surpassing it. I could not recommend this bong any higher for your first and maybe even final bong.
