I got an Indulgence and I am very happy with it. I got the extended cup too. I have a mini-review in the eastmall section.
There were some issues with the first run, but mine is perfect.(for me)
I am in earthmoving and do big hours, I used to take 2 510s, 4 901s and 4 901 PCCs and a couple of various super-minis with me and cigarette lighter chargers etc... cos I would suck a normal 510 or 901 battery flat in about 10-20 minutes, and working outdoors, I am used to chain smoking pretty much all day.
Now I take the Indulgence for all day vaping when I have a free hand and just 1 dpv9 carto kit/pcc so I can vape handsfree whilst on the machines.
It really has been a Godsend. (you dont wanna see me deprived of nic)
I can still use all my other newbie junk with it too, which is pretty handy.
I ordered a V1 Stick at the same time as the Indulgence, but I dont think I will ever use it.
I am sure the SB/GG/Chuck/protege etc would be better quality. (specially the GG) but in the end it is only a battery housing.
The main thing that helped me make the decision (I was contemplating the V3 Stick too) was versatility. I can use any atty, I have 2 big batts and 2 small, so I can downsize it if I am going out or something. (fits fine in my pocket.) and I can get 2 3v 123a batteries if I wanna go 6 volt.
