Hi everyone, we wanted to announce the Restrictor Disc (which seems timely for the above discussion). We feel this is a substantial upgrade, especially for inexperienced users, but really for anyone. The Restrictor Disc will allow for a larger flame and less concern about technique. It will work in all existing devices and will ship with all of our products going forward. Some earlier units have a smaller hole from intake to bowl and the Restrictor can be flipped and inserted into the glass intake, rather then down towards the bowl area. Our goal was to make our devices more consistent and accessible while retaining the large clouds we are are known for. The Disc is easily removable for those that prefer more manual control or have their technique down. The Restrictor is essentially a T-Nut that you can find at most hardware stores. The difference is ours are 316 stainless steel which are made for high temperature situations. Most hardware stores (Home Depot, Lowe’s, etc) will only have zinc plated, which is not safe to use with high temps. We highly recommend NOT using any aluminum/nickel/zinc parts for our products. We want to get these out to our existing customers in a fair and cheap manner. The Restrictor Disc will be available on our site by the end of the week and we will be offering a two-pack for $4.50 shipped until the end of September. After September shipping will not be included.
