I'll add my

on cartos with tanks.
- They are convenient, consistent, and easy to fill. Especially if you get one of those tank filling tools. The sharp edges on top of a carto can play havoc on the inner o-rings of your tank if you don't protect them.
- I've also had better life with punching vs slotting since those slots can also wear out your o-rings. Phiniac has a good punch that they sell.
- Life of my cartos has been dependent on the juice I use. Sweeter/thicker juices will gunk up my cartos after about 1-2 days while thinner juices will allow me to vape for closer to a week.
- I purchase my Boge cartos from iVape and maybe 1 in 10-15 are DOA. When attaching a new carto on my device I'll check the ohms and if it is significantly lower than what it should be then I know I have a bad carto.
- I can punch a carto, fill it, stick it in a tank and be off in about 5 mins and then only have to fill it once more halfway through the day.
