You must give this new habit some period of time before making decisions about another device purchase. Keep mental notes of what you did not like and use those notes to shop a new device.
Cost is really not a big issue
Cool. You are ripe to eventually purchase some really great custom battery packs!
I'm indifferent to the voltage I'm just looking for something that gives me a good fix. Not really worried about vapor output or throat hit I just want a good fix.
Well, if vapor production and throat hit are not important to you, stick with a typical e-cig device which supplies approsimately 3.7-4.2 volts to the atomizer.
The carts came from altsmoke.com maybe the batting was packed to tight to let the remainder of liquid below pass through but that's really irrelevant. If it happened once it could very well happen again and the risk of what ever that is doing to my lungs isn't worth it.
The filler in cartridges works fine. If you tax the device by requiring more liquid than the cartridge can provide, you will run it dry. You can either reduce the amount of vaping you are doing, top off the cartridges more often or have a ready supply of refilled cartridges on hand so you can swap them out when one starts running dry. This is a basic vaping ritual; not many ways around it unless you want to start dripping. Even then, you still need to stop, remove the mouthpiece, drip, replace the mouthpiece, vape and repeat as necessary.
The burned taste came when I dripped I have no idea why this is...
99 times out of 100, a burnt taste is a result of the atomizer running too dry, not anything to do with the cartridge filler burning. The second you detect a burnt taste, switch cartridges and/or add a couple of drops of e-liquid to the atomizer.
