So I really just want to take a minute so say thanks to Rob again for this great device. I'm on vacation with the family and the last thing I want is my vaping needs getting in the way of our fun. I did bring an Ego twist/Evod set up as back up but I mainly intended to us my Reo the whole time. Well I ended up giving the Ego set up away so I had no back up. But the Reo has been the most convenient thing I could ever hope for. The most I've had to do for it is refill the bottle and charge the battery. Oherwise it's been completely perfect. Dare I say it, I think it's been more conveient than cigarettes since I never had to stop and pick some up like when I smoked. Yup. This thing rocks and I'm just super happy Rob has made the effort to share his genius with us.
