I ordered the herbal tank for the Micro G. It came in and It gives pretty good rips for what it is because the chamber is super small. It's a good and bad thing because if you like to conserve your product this is for you, but if you like to enjoy a full session you may find yourself a little frustrated trying to get where you need to be. Loading the flower chamber reminds me of back when I used to hit gravs in college. I put bubble hash in it last night and this thing SHINED! Load up the flower chamber with bubble hash and you'll get probably 15-20 rips before you have to load it again, and that's enough to be fully medicated for me. And in true G pen form, neither the flowers nor the hash had a smell. Perfect for the car, hotel, dorm room, etc. Sent from my iPhone using Grasscity Forum
