I received the Ellia diffuser and I really like it.  I never had one of these before, I have had the night light with the wax melts but this is a lot better. Not only does it help with making your house smell good it does a other things as well.First off it is cordless big plus there! It has a light that's nice, but it also helps you to soothe your mind and help keeps you calm or it could also give you an energized effect, as mine came with an oil of rise up energizing blend oil ,but there are plenty others you could try. Like eucalyptus, lavender that are 100% pure.  I am really pleased with this and hope you try it!
