I have always been a BE fan,, but only had experience with the 112 and 901( based up to last purchase 4 months ago, don't know if there were manufacture changes)
and I was thinking about the 510s but until I hear some more positives I am going to hold off on the 510 purchase (that and I don't need any more as of yet)
My good experience with the BE112s on Janty Sticks is what made me consider and
buy the BE510's when they first became available. I like BE and a few of their
eliquids too. Always a good order cycle. But the nasty taste of the BE510 on the ones I got, anyway (early on) was take you're breath away terrible and it wasn't just the 'dry atty' thing. No amount of dripping gets rid of it. Now I've seen some other posts to where some weren't experiencing that and the one picture that someone posted that had the SLB (same thing with those), Joye and the BE - the BE showed some metal mesh at the base - but not like the Joye, so maybe they changed. I simply haven't had a problems with the Joyes I get from heaven gifts, TW and Janty so I'm not moved to 'try anything' else other than the HV and magnum stuff for other reasons. Also got one TW 'mega' atty that wasn't perfect either but one out of 5.
I haven't lost a Joye except 2 from pilot error (burned them out on a 5V) and lost one 'innovapor 'new atty' on a stuck switch on the Protege. No losses due to 'old age' - going 9 months but for the last few months I have about 8 ecigs going all the time so there's that to consider vs. someone who has one 510 kit and no extra attys. And I don't 'clean' - only when there's a performance drop and that really hasn't been an issue since using the 14500 batts. I recently switched an atty from a tornado to the bartleby to 'clean' it ;-) and it worked. Back on the tornado now.
