To tell you the truth I own the blu/volcano and the 510 manual..
And I use my blu/volcano more than my 510.. I've had both for about 4 weeks..
Initially I was dissapointed with the blu.. Inconsistant vapor/throat hit.. Less flavor etc...
But with proper mods.. You can make the blu/volcano an amazing ecig..
I don't bother with prefilled carts cuz quite frankly.. They suck..
I fill the inner cart with
juice (I use striclyejuice and esmokey)
..and use the PTB mod in conjunction with the spring mod (or Auto dripper mod)
and I get GREAT and consistant vapor with good throat hit.. Everytime..
The only time I get little vapor is when the cart isnout of liquid or the batt is about to die.. (which I do admit is more often than I like but with the pcc it's not an issue)
I do love my 510, but I love my blu a lil more (maybe it's jus because the pcc and the actual ecig is sexier and more functional (pcc))
trust me.. Do the mods, buy
juice and ull love your blu SO much more
I don't get why the blu/volcano is so looked down upon here.. It's a great unit if u give it a lil love and a boob job.. My guess is that the customer service/shipping is/was blus doom here in thus forum..
Anyway.. Good luck with ur blu, and give it a chance before u discard it
