i have the BLUCIGs, i got that as my start into the world of digital smoking. the concept is pretty cool, the reality not so much. the smokes are the same size as a regular cigarette, i think people call them "mini's". you can get one or two decent size hits before you have to put it down, otherwise you get a lot of week-*** hits. the carts flavors are ok. tobacco is a little sweet, very tastey. i dont smoke menthol so i cant review that one. the cherry tastes like cough syrup, the coffee tastes like ***, and the vanilla is pretty good (the best of the five). BLU doesnt recamend refilling their carts, but you can without worry.
the coolest part od BLU is the charger pack. same size as a regular pack of squares, holds 1 BLU esmoke, 1 battery that screws in and charges while you smoke, and 5 carts. the starter kit comes with a wall charger and a usb charger.
replacement parts are cheap.
overall....im using this as my backup set, while more parts come in for my penstyle. travel set for those long flights over the ocean without disturbing the people around me.
on a scale of 1-5, i would give this product a 3. just because the portable charger is really cool.
