This is a guest post written by Morandir835, an e-cig enthusiast, admin on the Vapor4Life forum, and a regular on their ECF sub forum. With the release of the new WOW juices comes the first real cinnamon flavor V4L  has ever offered. Cinnamon is not like any other flavoring for ecig juices, it's not only hard on tanks but every piece of equipment. There are a few things to look out for when using a cinnamon flavor. Tanks V4L  has sold two types of tanks, the metal capped and black Delrin capped. As I noted before the material used for the two tanks themselves is also slightly different. The only flavor for which this is an issue is cinnamon. Do not use the black-capped tanks with this juice. At the very least it will crack your tank. Cartos For those of us that refill cartos you might be used to getting 9-12 refills from a single carto before having to trash or clean it. You're lucky to get about 6 refills using cinnamon-flavored juice. My testing shows that the dual coil replacement cartos can usually get between 12-18ml's of juice through it before needing to be tossed. Blends There are a few cinnamon blends in the new line up. With the addition  of the OMG VV, and of course with USB passthroughs running at 5V, there is something important to note with these flavors. Cinnamon loves more voltage, the more wattage it gets, the more it bleeds through. What this can lead to is the cinnamon taking over a blend to where it's just like you're vaping straight cinnamon. With the OMG VV you can always dial down the voltage, but you can't using a passthrough. I suggest only using CoolCarts for the cinnamon blends on a passthrough. Throat Hit Cinnamon has been a prized flavor for vapers who want to use lower nicotine and still get throat hit. It's a flavor that has throat hit to spare by itself. If you're a throat hit junkie like me, you'll be pleasantly surprised at how much kick it gives. If you aren't though, you might want to cut your nicotine percentage down with any of the cinnamon-flavored blends.
