The Lookah Snail 2.0 is an update on the original Snail. The engineers heard you and moved the light to the top of the device versus being behind the wax cartridge. They also upgraded the chip inside to improve the overall performance of the device. There is still 3 preset levels of variable voltage that you can choose between as well as the 4 different options for wax coils. The Snail 2.0 also features a pre-heat function.
