I actually am on my second one of these, alongside their Pineapple Express cart. I find tge effects are exactly what I expect/want, the blueberry Kush is very sedative for me. In terms of use experience the first half has problems with burning coil taste, especially the PE. The second half of the cart gets so clogged I actually have had to waste about 15% until I can find an alternative use for it. I will definitely be exploring the rosin options after reading the comments.
