Like a kid on Christmas morning...the mailman delivered my RiVa eGo 1100mAh kit a little while ago, and I couldnt wait to tear into the package...the directions that came with the kit are easy to follow, the batteries seem to have some charge already, so one is on the usb port on my desktop the other I put together..filling the carto with low 6mg coffee liquid was also pretty simple to do. The initial few puffs were a simple learning curve. My office mate has no idea that I took a few nice vapes ...this is so cool I dont have to sneak outside in the friggin chilly rainy air anymore...on my last pack of analogs today ..wish me luck ..I think Im gonna like quitting this time and hopefully finally...
