I love the 510
I got my starter and supplies from Healthcabin
I got the USB Pass-through and PCC with batt and atty about 2 weeks into it as well...
ordered 3 extra atty's (one was faulty)
From what I gather, my product is made by Boge (copy, but reasonable quality)
Nevertheless, some things I've noticed thus far (6 weeks in)
The atty's are hit and miss...
you should get about 2 weeks MINIMUM from heavy-duty use on the atty's (meaning you run them WARM... I'll hit it three times, 5 secs per hit, over 30 seconds then put it down for a few minutes)
Although I have one atty that has gone 6 weeks without problems...
but my original 2 are showing 4 ohms... (a new one should be about 2.2 Ohms)
I find I hit the USB PT more often than the battery mounts....
probably cuz i do it while trading stocks (stress stress stress)
That might wear out an atty faster...
If the atty is showing 3-4 Ohms, I'll run it a couple seconds longer since the vape doesn't come otherwise, but I find it is still weak relative to a 2 Ohm atty...
I don't think the attys are usable after 5 Ohms
So far, my only battery issues came after about 2 weeks... where post-charge I had to trigger the batts 5-9 times before the LED would come on, but after a few days, that issue went away (I still have my original batts, and they work fine)
This could be due to the Protection Circuit kicking in...
Temperature? Current?
I think the USB PT burns more JUICE than normal (perhaps due to the higher current... 320mAh is more than the batts, I believe)
I go through about 1.1-1.2mls of Juice/day
Anyway,
6 weeks, 1 atty faulty, 2 atty's burning out, 2 going strong...
all batts are still good ( I get 1 1/2 -2 hours of steady use from them)
PCC is great, USB is handy but seems to burn more juice...
When the draw on the atty gets hard, I rinse it under hot Tap-water (slow drip) then dry it... Prime with a drop and fire away...
the attys seem to work better if you let it dry for 24-48 hours....
but don't forget to prime it with a drop of juice...
I don't believe dry-burning is good for Ni-Chrome
