Yes I got one on ebay for around 30 bucks in june and it works great for bho. I use it all the time. I have taken it to a few concerts and a canoe trip and it has been great. Fast and discreet, if anyone even notices they think e-cig.
I have soaked it in alcohol a few times so the black paint on the outside (feels like plasti-dip) is coming off the cartridge. The taste is way better than my friends micro-g. Although I think there is a bit more restriction in the dube so it does clog a little.
