This is probably the best vaporizer whip you can find anywhere right now--let me explain... All other whips I've used, you have to pack the material far from the vaporizer heating element--you'll also often have to pack MUCH more material because of this. The EZ change whip has a material chamber that is much closer to the heating element, allowing for clean, even vaporization of your material. You also have a cool to touch silicone EZ grip that not only functions as a safe handle to grab when operating your vaporizor, but it also acts as the "connector" which puts all the whip tip pieces together in a well thought out orientation. I never get material sucking through because you can place a fine mesh metal screen under the ceramic screen. Vapor Brothers put excellent craftsmanship into this whip and it definitely shows. If your like me and bought an aftermarket vaporizer (non-Vapor Brothers), stop thinking about getting this whip and GET IT, it's worth every penny... P.S. get these addons -> 14mm water adapter and the SOFT silicone hose.
