Not bad at all. The pre-rolls burn a little uneven but the flower inside is quality so I can't complain too much.
Was passing through for a conference and didn't know anybody in the city. Found the site, took a chance, and honestly the whole thing felt way less sketchy than I expected. Buds were fresh, dude who dropped it off was polite, and the price wasn't tourist tax either. Appreciate y'all.

Flew in for a conference and needed something to unwind after long days of meetings. Found them through a friend of a friend and figured I'd try.
