Yeah I think I just bought something else and I haven't even tried the thing that just arrived. hahaha
I love 510 manuals though they do have a short charge. I recommend extra charging cables (2 at home, one at work) and CHECK your 510 charging cables and make sure the mA output is around 150-250mA, not 400mA+. I have had 2 vendors screw up and give me Ego charging cables (same threading but 420mA output, damages slim 510
batteries). Boge 3 ohm cartomizers are very nice on 510. The hotter 2 ohm ones are only for the fat battery models like Ego and Riva. For 510 users - the Joye 510 mega xl manual batteries are very nice at home, even if you use the short ones when out. And the fat battery Riva 510 at Liberty-Flights.com - those kits are 3.7v and will vape all of your 510 stuff hotter. Ditto for little 510-threaded 3.7v box mods - you can even build your own with a kit from Madvapes.
I like KR808D-1 a lot too. I have manuals from SmokelessImage and Vapor4Life. I vape both 510 and KR808D-1, each with a flavor that contrasts the other's.
You should have spares for all parts of any ecig you depend on. And plenty of
juice - new vapers are the ones who run out. And don't be surprised if you get a hankering to buy something else by the end of the first month - typical. The curiosity is too much.
