So, I've been looking over here to find some advice about what device should I get to smoke spice. I see that lots of people suggest the GVG but it's kinda out of my budgect at the moment, so I'm wondering if Im better to go with the Classic Vapor Genie or with only a simple glass water-bong. You cannot see the vapour in the CVG, you can in the bong, still I guess the CVG vaporise better but I don't know how long I can expect it to work great. So if you have advices, it would be quite helpful. Thanks!

Another option would be a "machine bong" ... a ( small ) bubbler stuffed with brillo as a vaporization device. Or look up amor fatis "Inspirator" device, that should also work nicely i suppose. The VG is atill convenient but i've had good success with the machine bong/inspirator device

The Key v2 is a great option that will allow you to use a waterbong.. It's cheap and highly effective.

Try The Inspirator. All you need to get started is dropper stems, screens (pipe screens are incredibly cheap), and some rubber gaskets. It should even work without a bubbler.
