In my case, I got tired of constantly refilling and topping off cartos. So I became quite interested when bottom-fed juice mods appeared on the market, and bought a WetBox when they became available. It wasn't a particularly robust device, but the concept worked great for me. When I got wind of the REO Mini, which is a small but industrial-strength bottom-feeder, I had to have one. It hasn't left my hand since last September when I got it, and I've subsequently bought 3 more REO's, mostly for the luxury of having a different flavor available immediately. My nightly routine is to top off my bottles and throw the batteries on the charger. Every couple weeks I put on a new carto. Couldn't be much easier. One other factor that was important to me at the time was to have a device that used non-proprietary batteries, since the FDA court case was still in progress, and nobody knew for sure if supplies would be cut off with little notice.
