Just got my Justfog Minifit yesterday. Wow this is the smallest ecig I have ever used that is not a cigalike. It is about half the size of the myjet and a bit thicker. It is not readily available yet, I got it from China. It is a 350 mah battery, the pods hold 1.5 ml of juice and 1.6 ohm. It also has 3 led lights to show how much battery you have left which I like. They are around 15 to 18 bucks a piece, they come with 1 pod and a usb. The vape is actually pretty nice. It is not as tight as the myjet, but it is not too lose for a good mtl draw and i love my mtl really tight. It is extemely easy to refill as it has a little door you open to fill it. I may order in a couple more if I can get use to the looser draw, I could see me losing it lol. I just love how easy it is to re-fill compared to the myjet. But so far, in my limited use, i have had no spit back and no leaking. I will have to get back to you about how many re-fills a pod will last, but so far for a device this small, I am impressed.
I suppose my real "limiting factor" is a nearly complete lack of "disposable income" so I have to try to be somewhat cautious with my expenditures. Moreover, I still have to "play" with my "blend" of WTA with "whatever" as I really want to try at least 1 or 2 of the other Black Note flavors. My current mixes with the 50/50 BN and 100%VG WTA have been ranging from about 60-75% VG and ~9-14mg/ml nic. Thankfully, the Nexus doesn't seem to have any problem but the lower VG+nic taste better, are easier for me to vape, but don't seem to have quite the "satisfaction" level of the higher VG+nic. So, I want to get some 3mg/ml BN so I can keep a higher percentage of WTA without getting "nutso" on the nic. I'm hoping to be totally and "once-and-for-all" off the coffin-nails within the next month or 2. After that, maybe I can "experiment" a little more after reading more info from you and all the other kind members of this forum.
