I love to collect MODs, I currently own 33 and still collecting. Out of all that I own, this is the best one. I have the black and red MOD. I didn't buy it from Eciggity. This is packed with similar features as the Reuleaux models, this also has a touch screen which is a plus. When running on just two batteries, it lasts me a couple of days on heavy usage. Another plus is when you change coils/tanks, the MOD will recognize it automatically. I highly recommend to anyone looking for a gadget with ease of use and features. I'm planning to buy a couple more, one for my sister and another for myself to add to my collection!
