I went to the one in Ypsi the other day. It wasn't like the places in Cali or anything but I guess it's alright, better than getting it off the street. When I went they didn't seem to have much, 6 or 7 strains and most were near gone (It was close to closing). Of the strains nothing stood out as being impressive. I went there because I heard a friend of a friend goes there and got some crazy orange bud (supposedly, it was almost completely orange and smelled like oranges). But the offering were all pretty tame. I got Super Silver Haze and Chronic. The Chronic is a very uplifting, relaxing high which is what I was looking for. I haven't tried the SS haze yet, but the smell is very spicy, it smells like all spice. Each were $20 a gram, and the prices range from $15-$30.
Not much more info I can give as it was my first visit. All in all it's better than getting it off the street, but it's hit and miss on what strains are available.
