1. how long does your batterys last You? It lasts me all day. I vape it for just a little bit when it turns blue, then recharge the batts.
2. how long does the blue (low batt light) last you once it starts turning blue? I haven't tested this out yet. I will today.
3. i placed a LR atty on mine to SEE the cut off feature, and well it blew my atty and didnt shut off like in the youtube videos?? I'll have to test this out today, too.
4. atty connector was all brass color when i got it, now the outside has started to turn sliver? is that normal? inside is still brass color. Mine is still all brass
5. and after a while with the blue light, ill press the button, blue light comes on for a half second, i keep it pressed and i can still vape even when there is NO light ON? though i stop and swap the batterys before i get to this point. Again, haven't got to this point yet
and last how long do you let your batterys charge? my green light (on charger) will come on like after 2 hours, but the batterys dont seem to last as long if i let it sit longer in the chrarger. I take mine out immediately when the light turns green. I don't want to let them overcharge.
As far as attys blowing. When I got it, I also got 4 new Joye 510s. They were all harsher than usual in the "break in" period, but now they've settled to where I don't get that harsh taste. I didn't overwork them, I just rotated them and took a couple puffs on each until they settled down. I did try some of my older atty that I thought were dying, and they have been brought back to life using the Joker. I did blow one atty, but I removed the wick from it, so that may have had something to do with it. But now all attys are working great, just took that break in period.
Edit: My blue light came on and it lasted about an hour longer and then quit completely. I couldn't vape at all after it went out. Still gotta try the LR atty now.
