Experience With Honeystick Minimax Pro?

I recently purchased the HoneyStick MiniMax Pro, and while it looks cool, it might actually work a little bit too well. When I want to use my desired brand of cartridge (Space Vapes), and I turn the unit on, the "pre-heat" mode goes into effect and I can literally hear my concentrate sizzle (which cant be a good thing), and the first few vapes taste sort of burned, but that is even on the lowest temp setting!

Am I doing something wrong or is this unit only supposed to be used with thicker concentrates?
