This is a Dosisha wood-grain design circulator fan. It has a timer function and can also be used with aroma oils. Although there is no instruction manual, you can find it on the Dosisha website. Four unused aroma oil felt pads are included (1 attached to the main unit, 3 replacements). Operation has been confirmed, and the main unit has been cleaned, so it is ready to use immediately. The illustration of the power button is slightly peeled off, but there is no problem with the operation (photo 3). It can be used to improve heating efficiency. - Design: Wood-grain exterior and round fan - Power: Includes AC adapter - Timer function: 1H, 2H, 4H, and 8H settings available - Operation buttons: Multiple operation buttons are located on the top - Color: Brown
