Product review (2 stars): BEWARE
First of all it only has a 24 hour clock setting.. not 12 hour. Next, The clock turns off if the fan or lights are not active.. so at 00:30 when you get up for you snack you cant see what time it is until you touch the unit. This unit needs an outlet to be powered, took the cover off the electrical housing to see if i could hard wire it in.. and it cannot due to the spade connectors and 16GA wire. The fan is EXTREMELY loud on the highest setting. the LED lights only work as a nightlight.. do not expect them to light up your cooking surface. As for mounting... i am waiting for this to fall off the wall... they use cheap drywall anchors. The "cooker hood manual" refers to the screws as wood screws... They are not. The manual was also written in some Asian language and poorly translated into English. I give it 2 stars because it does look good and seems to be well made.  I do not recommend buying this hood.. There is a very good chance we are returning it in the next day or so.
