The duct fan works ok. Shipping box was good. Fan watts are 34 or 36 and works with 110/220 voltage. Air flow speed is below exception but works for my setup. I was planning to use it to outflow room air but I used it for inflow instead. Not recommending for out flow purpose. In box: manual + the fan. No Plug came with it so you have to buy it separately. Overall, if this last for two years it will be perfect.
