I am overall pretty pleased with the look and functionality of this aromatherapy diffuser. It has a lot of neat features and the color pattern on the top is beautiful and subtle. You can set if for continuous on or intermittent mist. You can set the color to one color, have it rotate colors, or turn the colored lights off. It aslo has multiple timer features with the option of 1hr, 3hr, 5hr, 6hr, and on. The mist level is high and it really puts out a cloud of the scent of your choice. It lasts all night for me in the continuos on mode with no timer. The only down side is that there is always about a 1/8 inch of water left in the bottom when it shuts off. This can be a pain to dump out each time if you want to change scents. So far it has not caused any problems but I do worry about possible mold build up over time if forgotten to empty after use. Overall I am happy with this machine; the pros far outweigh any possible cons.
