I bought two of these to help with the humidity level for my many plants. This is a USB humidifier (not stated in the description). The cord is only 80cms long. IMO not long enough considering the amount of moisture this little beast spits out. The mist reaches a max height of 25cms. Fine mist occurs around the humidifier after 2 hours. Maybe safe to put a cloth under the unit depending on the surface it's sitting on. No replacement wicks came with the humidifier however I don't think you'll need to put new wicks in for some time unless you're using essential oils in the water. It's just nice to have spares rather than going elsewhere to buy replacements. Wicks are big (10mmW x 170mmL) and thirsty! Delivery was super fast and notifications of my order were prompt and detailed throughout. Extremely happy with the service. Will be back again for sure.
