Zapped makes some good points.
Ikenvape only offers their punched cartos with two holes, and so far these have been working for me and my juices. But when I was ordering from Smoktek (my backup cartos for when Ikenvape are out of stock) I ordered one hole for 50/50 pg/vg blends, and two holes for any juices that have more than 50% vg. It's sort of a hassle to keep organized this way, but vaping is that important to me to go out of my way to be this meticulous to get the best vaping experience that I can.
I've always been suspicious of vendors that sell cartos without specifically identifying what brand they are. It's generally been my experience that off brand items are of inferior quality, and most of the items that come from China are knockoffs of genuine original devices that are of a higher quality.
My guess is the only people that purchase cartos or tanks from Provape are newer vapors that don't have a regular supplier of those devices, so who knows how long that stuff has been sitting on their warehouse shelves or who the manufacturers really are?
In fact, I was rather surprised when Provape began selling the Zen Atty Pro, as the other accessories that they had previously offered was very generic stuff. Sort of out of their nature.
I'm not judging FinchX for buying cartos and a tank from Provape, but I've been vaping long enough to have found specific vendors for specific devices/supplies that I trust are quality products. I would never have purchased cartos or a tank from Provape.
I never buy "starter kits", as they always include things that I will never use. I would rather buy the specific items by piece that I know that I can use.
For example, I get the following supplies from different vendors:
Batteries, Chargers, and Drip Tips:
RTD Vapor
Cartomizers: Ikenvape and Smoktek
Cartotanks:
IBTanked - Get Tanked With Us! (vendor allows you to create a pyrex tank to your specific needs.)
E-Juice: Virgin Vapors and Vaperite (both vendors customize your order to your specifications, use all organic flavoring and allow you to choose your pg/vg ratio)
