I've only used the Mutant as a dripper only so far but in that regard it's great. The vertical coils with cotton bacon prime don't sit a pool of juice like the cotton of horizontal coil does. This allows you to vape the cotton dry and cycle the cotton perfectly to keep that fresh cotton vape. I've had the cotton in 3-4 days and my desert juice still tastes great
Nice RDA great to build on good flavour and best price as usual from Vaping 101 .Very happy with it.
