I just want to add, I bought the VGO 900 sampler from Don (I have a lot of other 510 stuff) and it is a lovely PV. The atty has a slightly larger bridge than a stock 510 and provides a nice, smooth vape. I have used it dripping, and with a cartridge (the blank cartridges have polyfill in them, I don't like the way it tastes so I removed it and used blue foam plug instead). Make sure to insert the cartridge fully into the atty so there's no gap. I got virtually no leaks even with a thin
juice - just don't leave it standing on end for hours, or it might leak some. Lying down, no problem. I didn't notice any leaking with the polyfilled cartridges, but I thought it didn't feed the atty very well - it went dry fast, and when I pulled out the filler there was still plenty of
juice in it - that was the point where I changed to blue foam. I go through about 2-3 cartridge refills on a full charge, it's so nice to have a battery that lasts!
I did some research on the VGO from other suppliers. Apparently some other versions may have an LED on the end - the one from Don has a flat, polished-silver base so you can stand it up. Much less ostentatious.
It's also worked fine with a Joye 510 atomizer, Boge 510 cartomizers, IkenVape 510 cartos, and even my 808 cartridges used with a 901/510 adapter from MadVapes, so I'd say it's fully compatible with other 510-threaded parts. It's solidly made and I'm very glad I got it. Plus, it's gorgeous!
