Aight. Got mine in today. Put in another battery (to let the others charge up fully) from my ego kits, filled the little tank, and took it with me to play some disc golf.
First of all, the Ego brand sure bounced back with this one. The tank was hit or miss for a lot of people, but this one should be a hitter all the way. Holds a good amount of juice, consistent flavor, good vapor and TH (I believe it is a low res atty), and a half filled one lasted me a good 4 hours, and I am a HEAVY vapor when playing me some disc golf.
Couple of quirks I was annoyed with. The overall design is great, but not if you have to move around a lot with it. I couldn't keep it in my back pocket, like my Ego, due to the whistle tip and the container cover being a rather loose snap. Reaching into my back pocket and pulling out the top two pieces became quite annoying, and sticking it in my bag leads to problems of it falling out and getting lost. Great PV if you have it sitting somewhere, or it is easily accessible and doesn't have to move much. Going to stick with the regular Ego when I have to be out and about.
Those would be the only problems. Very user friendly. 9/10.
