very nice but too small [SEP] very nice diffuser offers a steady stream of mist at a generally good speed i do like that it offers the sleep mode which slightly reduces the volume of steam omitted i just wish it was a bit bigger it runs about hours on full power on sleep mode i ve found it goes about hours it doesn t last all night so it s not great if you re looking for an all night humidifier it s a nice diffuser for a small space i feel like it takes a while for the aroma to fill my bedroom and then it s practically time to refill it the colors are nice on the light i haven t had to clean it yet but i ve been letting it dry out each day so it s not sitting wet between fills they need to offer a bigger version because i do like it a lot
