am happy with this product, however I feel there could be some improvement. While it does work well to keep moisture in the air, if the temperature of the room is cooler than 70°, the mist stays low to the ground and settles on surfaces. It would also be helpful if the spout on top could be moved to direct the mist. 
                    Calcification is an issue even after only a few months of use and regular maintenence. 
                    The light makes a wonderful night light abd i like that it can be used without the light as well. It would also be nice if essential oils could be used in the device, however I understand that it wasn't designed for such things. 
                    All in all, I highly recommend this product for both parents and anybody suffering from allergies and altitude sickness.
