Yeah they do suprisingly hold quite a bit of liquid. They actually hold alittle bit over 2ml of juice, but 2ml will just about fully fill them.
What PG/VG ratio is the juice your using?
All cartos need to be kept wet so they dont burn, but LR cartos especially have to be kept wet bc they will burn even easier if they get dry.
Thats why I really think a syringe is the best way to fill bc it takes absolutely all the guesswork out of filling.
I would at least use a syringe for the first fill, then if your juice isnt really thick, its easy to just drip fill some just to top it off. Thats what I do and it works well. I never let them get below about halfway full bc then it only takes alittle to top them off and then drip filling works well. If you let it get real low though I think its easier to just use a syringe and completely fill it again. I know its hard to tell right now, but after youve used them for alittle, youll know when they should be topped off. I normally top one off when the top of the filler starts to turn white again. At that point its still prob about half full, but it just makes it easier to top off. And then you never have to worry about burning one bc it got dry.
I only use one juice per carto and never put another juice in one. I just find it easier to keep putting the same juice in bc then you dont have to worry about trying to clean them.
I buy all my cartos from CCV. Their prices are good and the free shipping is def nice when your just ordering some cartos. When they are backed up with orders it can take a few extra days to get to you, but its really not that bad. Personally I think people make a much bigger deal out of it then it really is. You shouldnt wait till your on your last carto to order more anyway. I order more when I only have one 5-pack left. Then if it takes an extra day or two it doesnt matter bc you still have 3-4 left that will hold you over till your order comes in.
I also like CCV bc they guarantee all cartos. Most vendors only have a DOA warranty. Ive bought prob at least 20 5-packs of Ressurectors from CCV and have never gotten 1 DOA. I did about a month ago get a 5-pack that had 2 cartos that didnt wick properly. They were fully filled but for some reason they were acting like they were dry. It obviously wasnt CCVs fault and was just a manufacturing dud, but I called Andrew and let him know. I didnt even ask for a replacement and the next day I got an email that he sent me another 5-pack for free. I thought that was really awesome. He doesnt even make you send the defecive ones back, which is really cool actually. Alot of vendors are willing to give a replacement on something, but you first have to spend more money to send it back to them, just to get a replacement. Thats what I liked about CCV, he is willing to replace a carto if theres a problem, even after a few days of use, and doesnt ask questions or make you return the defective ones. Andrew really cares and just wants to keep his customers happy, and that makes him a quality vendor in my book.
If you like those cartos I would def buy 15-packs. You get them for alittle cheaper when you buy 15 and you also get a syringe and a free drip tip when you order 15. Its a good way to collect a few drip tips since your getting them for free. I just order a different color that I dont already have every time, then put a different colored drip tip on each carto you are using at the same time. I find thats a really easy way to tell what flavor is in each carto. Lately Ive been vaping 3 different juices alot. I know that the carto with the blue swirled drip tip is my coffee vape, the sold dark blue drip tip is my tobacco juice, and the green drip tip is my sweet flavor vape. Everyone has their own method, but I find doing it this way works really well for me.
