It lets you change how the vapor is. You can make the coils hotter or cooler. You can change it for different juices. You can change it for different attys. You can keep a constant voltage.

A freshly charged battery is about 4.2 volts and you can run it down to 3.2 volts so over the course of battery there is quite a difference in the voltage used. It's not as bad as it sounds cause it drops off quick, slowly run through the middle and then sharply again at the end. With a VV device you can set it to 4.3 volts and it will be 4.3 from the start to the finish.

Depending on how good your taste is just about everything you change can affect how your vape tastes. The will vary from juice to juice. One juice might be fine at 4.3 volts and you will like another at 3.7

You might have 2 different attys, say a nautilus and EVOD, and one always tastes better .3 higher than the other.

One day you might want to turn the volts up to get more vapor and the next turn it down for better flavor.

Volts, watts, and ohms are related by ohms law. If you know two of them the other one pops out. So, for a resistance changing volts will change watts and vice versa. The theory is that a vape at the same watts will be the same so if you have a 1.2 ohm atty and a 1.6 ohm atty and you like to vape at 9 watts you could use an ohms law calculator and set the voltage at 3.3 and 3.2 or you could set it at 9 watts and the VTR will check the resistance of the atty and set the volts to 3.3 or 3.2

It gives you one more knob to twiddle to get the vape you want.
