The PureSpa XL was very easy to not only set up but it is smaller and more convenient for use in my bedroom. The mood light and aroma diffuser are bonus features for me since i really just needed a humidifier (and i’ve never used an aroma diffuser before). Filling it and testing it out was easy and i liked having two different modes of mist output. The changing colors will be nice for when i want to relax before bed!
