Cave very well finished, cedar drawers in Spain (and not the tackle as my old cellar). Hygrometer precise, for against the humidifier comes with a 100 ml bottle that I had to completely empty the humidifier. I could not mount humidity after 3 days because I had paid in that half of the bottle ... We must fully pay the bottle and wait crystals absorb all the water until they flatten against the ventilated wall of the humidifier (crystals have a thickness of 3 mm at the base). It is not explained in the booklet? Besides this lack of explanation, I am really happy with this purchase. The packaging was really neat again.
