Just to add about the Haze: one of the reasons for the 2 bowls is to fill each with a different product or to use different cans. It comes with convection screens and conduction screens so you can use both. I don't use concentrates and it's great for herbs. The next Haze product will have 4 sections instead of 2 for the same reasons. It's also a great company- when they upgraded from the 2 to 3 owners of 2 could trade theirs in for $99.The lack of resistance makes a huge difference. I've been so involved with my milaana and vapcap I forgot about it. I'm going to get mine out and use it again.
