Get a 901/808 - 510 adapter for your Volts
808s are better than 510s for a number of reasons, so I'd be tempted to get an adapter if I had to use 510 gear and wanted a small ecig.
leftfeild.. I'm curious about what the reasons are. Been trying to research but except for the 808 having slightly longer batt life and 1/2 or 1mm larger, I don't see a huge difference? Granted I'm talking generically & not about the VOLTs (haven't looked close at them). I've heard that the 808 carts seem to deliver more vapor.. Is that one reason?
I only started 3 days ago with a Blu, and I've ordered a 510 to 808 adapter, some 510 cartomizers and one each of a 510 and 808 clear cartomizer because someone mentioned the 808 carts seem to work better so I thought I'd try one with my 510 batt. But after my order I found out about the short batt life of the Blu '510'

so until I decide if I'm going to go for a way big batt I ordered 1 each of a 510 and 808 XL size batt.
I'm figuring that since I've been tobacco clean after 45 years with these things, It's worth a couple hundred bucks to experiment until I get dialed-in.

So, your 808 over 510 thoughts? Thanx
