A couple of things:
The flat tip carts on the 510 disposables are not 901 carts. They're made for these disposables and they fit, in my opinion, better than the round ones (for the 510 disp.)
I've used
three different 510 disposables and every one had supreme vapour from the first hit. I've never used a Joye 510 atomizer but I have used a manual Joye 510 battery on the disposable atomizer, and other than the fact that manuals generally give more vapor than automatics, the vapour production between Joye and disposable 510 was virtually the same. In fact the auto/manual difference didn't really make that much difference.
In other words, vapour production on these disposables ROCKS. You want to be careful dripping with the automatic
batteries as they're unsealed, and 510 carts are big enough to be useful. I use the foam plug myself, but you can drip in a pinch if you're at one of those times when you're not sure if you need more
juice or if your battery is close to needing a recharge. Also when you get that harsh or burned taste, dripping is great to get rid of that.
