You were right Crash, I wasn't disappointed.
I got my KR808 yesterday from Eastmall so here's my take on it and a question or two.
I ordered 8mg carts with RY4 and US Blend/Mbro .
There was minimal packaging which I was pleased with. Everything came in bubble wrap, no fancy magnetic seal box which only end up filling up my recycle bin anyway.
Quick summary for those not bored enough to read lots of text :
Battery life : 2.5 hours chain-vaping.
Vapour production : Light
Flavour: Epic
Throat hit : Very Strong
Draw: Very light
Build : Excellent
PCC: Great except for the short USB cable(is it supposed to be retractable?)
The first thing any regular vaper will notice is the throat hit, it's very very strong, a little too much for me at first, caused me to cough for the first hour or so but it's not really unpleasant. It's not down to the juice either, I refilled later with my regular 11mg Hilton and the throat hit was just as apparent.
Flavour is immense, best flavour I've had, those cartomizers really bring out everything and I could taste subtleties in Hilton that hadn't been apparent with a 901.
I was chain vaping these much of yesterday so I could get a feel for battery life and taste and check for burning of the carts as well as getting used to refilling.
I refilled at the same time as the battery died which was 2.5hours of continual vaping and that was solid right through to maybe the last 10 minutes or so where the taste dies off. I imagine normal usage I'd be getting 3-4 hours use per charge, when considering you get a PCC, battery life should never be a problem. There was no burning or scorching of the material but the cartomizer does get surprisingly hot so I could imagine how this would occur using a manual battery, passthough or mod. The 7(?) second cut off is probably much more important in these devices although there's no wait after the cut-off.
Overall I'm very happy with it and it will be perfect for when I'm vaping in public, the reason why I bought it

p.s. Crash, did you time how long one of battery charges from the PCC take?
