I tried Nana Glue and wow, it was immediately noticeable how strong it was. The high made me feel quite euphoric and creative at first, then slowly transitioned into a real physical relaxation. Towards the end, I was definitely paralyzed on the sofa, not overly lethargic, but definitely cozy and calm.
The smell really surprised me: at first, very gas/diesel notes, plus an earthy, woody component. Sometimes there was also a slightly sour scent, almost like overripe banana.
The taste was similar: gas and diesel dominate, with a hint of sweetness, banana, and in some phenotypes I tasted slight dark chocolate or coffee accords. There was also something malty and spicy in the aftertaste. 
Visually, the buds look pretty impressive to me: lots of resin, really sticky, dense, thick trichome layer. Green with often darker/purple hues and orange hairs.
