Purchased my first vape from a tall male clerk(can’t remember his name but he rides a motorcycle), and asked for a little guidance. He was direct, knowledgeable and polite. He was also on point with this device. Great piece guys! But want to giv props wear they are due. The clerk also suggested some nic salts per my taste preferences. Was a little a bit trepidatious but damn, that stuff tastes loads better than the Marlboro flavor I was looking for! Thank you Chu Chu
