I've been vaping since Sept. 2010. Started with Smoketip and I went away from their batteries as I like the manual button better. I've bought juice from vaporbomb to refill these carts, but still nobody has a good cart like Smoketip. I've tried different mixtures of PG/VG, but with all the juices I have used it has an odor no matter if it is 100% PG or 50/50. The 100% PG I get from vaporbomb produces very weak vapor. Smoketip uses 100% PG and it gives off good vapor and good hit and their menthol kicks .... And I don't know how they do it, but it is totally odorless. They recently changed their menthol flavor a little, so I am shopping again. Anybody else sell the carts already to go like they do for less than $2 a cart? Or anybody else know of a really good methol flavor that produces no odor?
