Very cool thing) i'm delighted) there are two functions: continuous steam and cuts, after switching on steamed minutes after 3. i do not know how much humidity level will rise, but the steam jet is good, for such a small size) noiseless, barely audible only steam. The wiring is short, i will buy another, the usual usb cable will fit. Delivery 3 weeks, everything came intact, i recommend it, i hope it will not last a little)
