Got my first order from GP the other evening, and I'm very pleased!
The manual XL KR808 battery is awesome - wish I would have went with the XLs to begin with. I really like the matte black finish. I'll be back for more of these! The button doesn't seem as wonky as the regular batteries I started with either. (they were from a different vendor)
The blank cartos work nicely

Wish they were soft-caps - only because they seem to work better for me when I use the cap-fill method. The hard caps I have to take out and wipe out after I fill them or I get a mouth of liquid

That might just be me and my noob'ness though lol
The liquids are good so far - except Lemonade

ick. Tasted like a burnt lemon peel smells.
But the Cherry/Blueberry one is good, and the Chinese Gooseberry is cool too...not sure what a gooseberry exactly is, but it tastes good! Kinda watermelony/kiwish
Those are the only ones I tried so far, good vapor and taste - strong TH. These are my 1st thing in the morning juices (18-24mg), and they satisfy the need!
Thanks Rob! I'm happy to find a vendor in PA.
