I\'ve been using the mega 510s for a long time. they are great because they fit blu cigs cartomizers and they don\'t carry a manual battery!! I usually get my titan 510s from Totallywicked.com. They have them for 14.99. but you guys had green & copper colored. And i like the way your choices tell you light color!!
I've been using these for a while now. They will go out after a while so I buy a different color each time to keep track of which ones are old vs. new. The work great. I never run out of battery now. Just keep a couple of these with me on road trips and I'm good.
This item lasts twice as long as the standard battery that is supplied with the Joye 510 and works well with the standard charger. Well worth the extra cost.
