I'm actually loving the PigCig. I posted my impressions of it in one of the PigCig reviews, but here is a quick rundown. Before this PV, I've only been using 510s, both the standard batts and fat batts (650 mah and 1000 mah). The PigCig is a 650 mah batt, but it's slightly shorter (3mm) than the eGo 650 mah batt. I chose the chrome finish, and it's very sleek looking; aesthetically, I prefer it over the eGo. Also, the activation button feels a lot more sturdy. There's some debate on whether or not the PigCig really runs at 3.7v under load, but its performance is definitely better than the eGo. I have 510-808 and 808-510 adapters so I tested kr808 (2.4Ω) and 510 (2.6Ω) cartomizers on both battery types. For me, the PigCig is the better of the two, but I'll still keep my 510 stuff as backups and for friends that want to try
vaping.
With respects to the LeCig cartos, I emailed them and was told that their standard cartos resistance is 2.4Ω and the mega-cartos are 2.3Ω. I also have used V4L Wow cartos (2 - 2.2Ω) on the PigCig. For me, they are on par with each other.
