I was having this problem for a while, especially with the tobacco flavors. The way I have figured out how to tell when the cart is low, is if it starts to lose its flavor, I try one more more time and blow the smoke out my nose (sounds weird, but works for me). No taste or burnt taste I put that cart in my refill pile.
Don't know if it will work for you, but you could give it a try.
Note: V4L does NOT either suggest nor endorse drilling a hole in the side of your cartomizers.![]()
I found the same problem. Just today I was about to give up on my last 5 cartomizers as they just were not taking any more than 10 drops anymore, were not producing much vapor, etc. Then I just thought what the heck I'm gonna try rinsing these out.
Took them to the sink, ran warm water through them. Blew them out, and repeated that process about 20 times a piece. Man they are pristine white inside now just using warm water!! Blowing them out well they were pretty much dry also - so one of them I just went straight back to the desk and filled it.
That thing took **28** drops of juice!!! and it still was not overflowing at all. just starting to show moisture on all sides. So I put the final drop on the opposite side. Gave it a good shake down, put the tops back on and screwed it down on a fresh battery.
About 5 puffs later - this thing is like a brand new cartomizer!
So I have refilled all of them and they all work pretty close to new or just as good. Me likey!
Hope that helps some,

I've done it every way. I've found the best to do it through the "suck" end with a 1ml hypodermic needle. You can guage the distance you need to place the needle into the cart by placing the needle againts the side of the cartomizer so you know how far to go down. Fill the needle with .5 to .8ml go in the suckhole at an angle until your half way down the cartomizer press the plunger and your done. Vape away. Takes less time than removing the cap. I've actually filled 1 cart 23 times without ever removing the top and it's still going strong.![]()
Ya think an insulin pin would be long enough? Or do I need a 1" probably?![]()
The juice might be a bit thick for that thin of a needle? I open even my brand new cartos and make sure that the atty is centered before use, and recenter each time I refill. I guess I want to see that things are looking good inside too.
What is happening is generally I top off through the battery end to try and extend the cart life. Sooner or later I get that burnt taste. A couple of times I've gone ahead and pulled the guts out of the carto to see what I'm burning and it is always the filament burning through its wrapping and usually also burning the batting.
It looks like I've found some good new advice to try here:

In one of those threads the man who knows said:
you are puffing too hard, soft....long, and NO issues then, you will also get much better vapor, as welll

Treat the VK like a women(man)soft, and gentle, you will be rewarded
Looks like I'll be trying out some new draw technique and refilling strategy.
