Modnote: Cross posted threads merged. We have been around since 06' and primarily sold wholesale to retailers. In late 2011 we decided to go consumer direct, and in early 2012 we launched jetwaterpipes.com So, to get to the point, you can use any 14mm GonG attachment or hook any vape to it through the 14mm GonG downstem.The JET's design ,function, and production methods are like nothing else on the market. We are not glass blowers, but rather have engineering and machining backgrounds. Using C.N.C. machines we are able to achieve dimensions and tolerances that glass blowers cannot. When we designed the JET we used computational fluid dynamics which allows to break down every aspect of a software model in how it will react with a fluid,air, and pressure. This enabled us to achieve mathematically and geometrically perfect bubble formation, which is key to filtration and smoothness. This design allows us to achieve as many bubbles as possible, while keeping them as small as possible, with the highest surface area per bubble possible. This also allows for the bubbles to not meld together ensuring that they will stay in contact with water for the longest amount of time possible. The diagram included helps to illustrate this point. We are not knocking on glass whatsoever and know that most everyone prefers glass which is why the stem accepts any 14mm GonG attachments, or vape fittings! The JET is also damn near indestructible and guaranteed for life. The JET is composed of the finest and highest quality materials available. The base, cyclone filter, mouthpiece, and carbslide are composed of acetal, which is an engineering thermoplastic used for prototyping. We chose Acetal because of its excellent dimensional stability, ease to work with, and how safe it is. The tube is composed of BPA -free polycarbonate which was chosen for it's incredible strength, aesthetic,ease to work with, and safety. The stem, diffuser, and included bowl is T6-6061 aircraft grade aluminum that is type III hardcoat ceramically anodized at the molecular level to keep the aluminum inert(safe) and incredibly heat resistant. We are releasing a new attachment for the JET very soon, before x-mas. They are stackable diffusers. We designed a new diffuser with 56 percolation holes and will take the JET from 49 perc to 320+ perc! Yes I said that right, 320+ percolators! If anyone has any questions or anything please don't hesitate to ask, we love feedback! I also have plenty of reviews, and unbiased user reviews available so don't take my word for it, find out for yourself why we are "The worlds most revolutionary waterpipe!"
