How long do these batteries last? Weeks, months? One of my 510's went from live to dead in @ 6 weeks. The regular 510 costs maybe $10, the ego costs maybe $20. But if the ego dies in 6 weeks, is that cost comparable?
ps. where do you get the adaptor to charge your ego on a 510 charger?
thanks friend
