I've had the pleasure of using this vaporizer for the last 2 months and now that it is shipping, I thought I would put together a brief online instructional video. The VHW allows you to retrofit any existing waterpipe that you may own and transform it into a vaporizer. The air path is 100% glass which results in tastier vapor. It works much like the whip hoses, but instead of bringing the whip to the heat source, you bring the heat source to the waterpipe. The video should explain the rest.
