I sent my Blu back and ordered a Sidesho. Ever the impatient one, I picked up an Envy starter kit to tide me over while I waited. It came with 1 battery, 1 atomizer, 1 usb character, and 5 pre-filled carts. While the battery charged, I gutted the first cart and replaced the contents with blue foam and some nicer juice. I wasnt expecting much from it, but I have been pleasantly surprised. The vapor generation has been pretty good and consistent. I cant speak for the traditional filler, but with the foam it empties the cart. In all, it has pleasantly exceeded my expectations. Now, Im not saying that anyone should rush out and pick up an Envy. The starter kit runs around $50 and you can get a lot more for your money elsewhere. If youre not into refilling, the prefilled carts run a ludicrous $10 for 5. However, if you absolutely have to have something right now, the Envy doesnt seem that bad.
