If you are refering to this pen www.o2vapes.com then yes. I have one and they are all over Cali and Michigan. Emerald Green in San Fran is where I purchased mine. They hit very smooth. Make sure you buy the refillable cartridges on their site and fill your own. The stores charge WAY to much for the pre-filled.
I have head of them and use their pen. I love mine as do my friends. We love o2vape and their customer service is so top notch on returning calls and for warranty issues ..We use the slim kit go get one at www.o2vapes.com
