That's right, I'm talkin' about the Vision Nano. For the longest time I was looking for a clearo to replace cartos on my eGo batteries that would still accommodate my cones. I tried the CE2 which does fit under the cone but the cone cuts off the air supply making it impossible to get a hit. I do like the CE2 as well but more for taste testing new flavors. Speaking of which, the Vision Nano is awesome for taste testing since the wick is so small and its a bcc. I prefer not to use top coil clearos with longer wicks for taste testing since the wicks hold the flavor from the previous liquid. I used to use cartos which was crazy expensive, and I know there are atties and drippers, but sometimes you need more than a few puffs making the Nano the next best thing, especially for just a few bucks. I also like that it comes in colors and their own mouthpiece. If you haven't tried a Nano yet here is a really informative Nano article for you to check out. They are 10X better than those T4 or E-Smart clearos with the short wicks that they have. I hate to sound like a commercial but if you like he T4 you will love the Nano!
