Lets start with a little electronics background. Resistance (the ohm reading you see) determines how much current (electrical level, not to be confused with electrical volume which would be voltage) is passed to the end device. The lower the resistance, the more current that passes to the circuit. So, when you use a low resistance atomizer, it allows more current to pass to the heating element causing the liquid to burn at a faster rate and higher temperature.
Think of it like this, if I put an egg in a pan and turn it on low, it will eventually cook to a soft robust texture. If I take the same egg and put it on high, it will cook much faster but will likely burn and taste like crap.
Same thing here, the faster and hotter you make your e-
juice the stronger and closer to a burnt taste you will get. The slower and lower temp will make it more robust but decrease vapor volume. You need to find a happy medium that fits your taste and sensations. Try a couple different resistances (the CE4, CE4V3, and CE5 all come in 1.2 to 2.8 ohm) and use a variable voltage battery and you will find exactly what you're looking for.
Remember, there are hundreds of brands of cigarettes because everyone likes something different. So don't expect "one size fits all" in the e-cig world. You will have to experiment and find what you like. Even if you spend $500 on different hardware you will still save money over smoking!!!
