The device is very bad.. and I never advise anyone to buy from it.. The device is beautiful in appearance but it does not work at all.. contrary to the marketing videos.. I bought a device a year ago and I am suffering that it does not produce fog and every time I contact the company they say the problem is with you.. then they asked me to buy a new atomizer and the shipping is on my account even though they said that the old one does not work and then they asked me to buy new filters under the pretext that the old one does not work.. and also the payment and shipping are on my account.. and after that they said that we are not responsible for the device
