Hi, dancergrrrl and welcome!
KGO is a very good option.
Just to clarify - the way this works is that you should buy juice / e-liquid from one of the very many vendors that sell it, and you will then fill your cartomizers.
It looks like you want to try the Vision eGo clearomizers which is not a bad idea at all either. They are transparent so you could just get a clear one and it will go with any color
There are a couple of things you should know about them. I am not sure why they say the lower resistance ones do not work on the KGO - I am using one right now and it is a 2.2 Ohm - at a voltage that is much higher than what the KGO puts out and there is no burnt taste. In fact, to get a warm, full bodied vapor on the KGO you need "low resistance" attachments. The magic numbers are 1.7 Ohm to 2.5 Ohm. And stay away from cartos marked as "dual coil".
The other thing, that is usually not obvious, is that as you vape with those cartomizers you need to get in the habit of tipping them downward from time to time to charge the wick and coil. If you don't, then it may happen that not enough liquid gets to the coil and then you will get a burnt taste.
Next, although you can refill your cartomizers many times, you need to remember they are ultimately disposable and will break down at some point and you must have a few of them - don't buy just one.
Finally, there are other options of "heads" you can put on your KGO. In time you probably should explore some more of them and see what fits you best. My advice is that no matter what else you get, take at least one pack of these
Boge 2.0 Ohm cartos so you just have them. They offer a very consistent vape and are the "default" head for many people. You will need to learn to fill them, as they are not as straightforward as the Vision eGo.
Good luck! You're off to a great start!
Thanks all!
I was going to order tonite and of course have become confused

I was ready to order the
KGO V2 Vision Kit in glossy pink and figured I would go with the 1100mah (that's a longer battery right?) but then I saw this in the description and got scared:
V2 Vision Ego Cartomizers (Standard Resistance only, LR will produce a burnt taste on the higher voltage KGO batteries)
I want the black cartomizers to go with the pink but it looks like they are out?
Am I getting this all correct? I was so excited to buy it tonite!
Oh, and if I do get this, do I have to order "juice" or liquid to go in it also???
