This steamer works properly. Although to switch the temperature measurement mode from the faringates to degrees celsius did not work. The device is compact, looks stylish and even elegant. Very satisfied with the effect of steamed herbs. The power of the battery lasts for three people to enjoy dry smoking mixtures and have a wonderful time. For better retraction effect, i recommend adding a membrane from the gauze bandage, as a filter. I recommend to everyone who cares about their health to switch to steamers.
