After using my new eGo twist with the included claro that the kind lady filled up at the shop where I got it. I got about half way through the juice that was in it and it quit. The heating element went out. I guess I had approximately 5 hours of vaping on it. Called the shop and they were kind enough to allow me to bring it back (48 hour warrenty.) Also found that the flavor I thought tasted so good at the shop started leaving a really strong after taste. It was peanut butter @ 24mg. I filled the second claro (I hope I'm learning the right terms for this) with a different flavor and lower strength 18mg. How many of the claro's should I have on hand? Going back to this shop is a extreme inconvience due to the milage I have to drive. Suggestions to help me out?
