I have had the best experience with Freshsmoking! The staff is great, they respond to your questions so fast (same day)! The product is great. I have the 510 it's so nice it's smoking with out the bonfire taste. I love it! I'm hooked. My boyfriend is an ex-smoker and I was using the 510 2 foot away and he couldn't smell anything. He kissed me and asked if I quit smoking again. I love it, it's smoking w/o all the bad stuff (smell, taste, health side effect, coughing) I could go on and on. I'm the 3rd person at work to buy this and everyone now wants one. I highly recommend this! If you have any questions, ask them in the contact us and you will have a reply same day. Happy non smoking :D
