My Zeus just came in the mail and I must say it is a thing of beauty!! I ordered the green and it is a beautiful color. I now want to get the blue and hot pink. I ordered both the dual and the automatic batteries to see which I would prefer and right now I am using the automatic. Okay...I just tried the Dual and I think I like the automatic better...we shall see. I am sure the Zeus will help me quit smoking analogs...I just need to keep them away from my reach to break that habit and use a little bit of willpower...of course I know in the morning when I wake up it will be much easier as I will start out with the Zeus and not any analogs at all. I am very happy with it so far. I got the 650 and I think it is a good size for me as I am sure you all know it is almost an inch longer than my long Vapor Kings. Wanted to let you all know it came today and I am thrilled with it!
