I am a rookie casual smoker, and have been using the Helix for the past years, as I like the smoother hits, I have other big water pipes but are way too bulky, too much work for a smoother hit, so looking around; I got me the COFFEE MUG 2 weeks ago... Man o' man!!! I love it so much, it hits very smooth , small enough to be able to keep it concealed, and with the small bowl; I can always have fresh hits! Perfectly designed, Grav always on point . My higher self is very pleased with this product, Thank you Guys!!!
