shanagan, how is this, i will send oyu a sapphire that i used and still use and is at 23 to 25 fills, never modded and works as good as day one, im putting it to side, if this works for you then your original sapphire was bad, if it doesnt work for you then your vaping habbits, juice or your battery could be the cause, does that sound like plan? i cant tell much by guessing but we can see where the issue is and take it from there.
I think it's a great plan - probably the only one that would help narrow down wth the problem might be. My most recent order # was 1028748 for the shipping details.
