I am very happy using this unit. Came in pristine condition and works accurately as it had been advertised. My only regret wasn't getting it sooner. It comes with a humidifier (hooked up via a scratch-resistant black velvet pad to guard the wooden humidor box from friction harm) and hygrometer. https://medium.com/@refinedtraditions/the-ultimate-buyers-guide-to-humidor-cabinets-09e99f97a801
