This company is nothing but a ripoff. If you are considering e-cigs, I suggest you try a company who offers a 100% refund in case you find out you don't like e-cigs or have an allergic reaction like I did. I tried the cirrus 3x product, was not impressed with the smoke, and I also found out I am allergic to something in the cartridges. Of course, they are charging me $63.00 for a restocking fee, which seems pretty high since I mailed the product back to them the very next day and I don't think it will cost them $63.00 to restock the cartridges or anything else in the kit. I wonder what they do with the items they restock, maybe refurbish and sell them as new to other customers. When I was on the phone with customer service they said each battery costs $140.00. And one more thing I would like to mention, the 2 yr warranty that is included with the kit is only a manufacturer's warranty, it is not the extended 2 yr warranty they sell.
