Product review (1 stars): Bad quality Not as good as I thought
Update 1 year later: It's cheaply built! the buttons are plastic. One of the buttons cracked after only one year(photo attached).  Not to mention the light start blinking no longer than 1 month use. Both the button and the light don't seem like they're replaceable.
Original review: Suction not as strong as claimed. My whole floor smells when cooking. Filters are Easy to wash and clean. Overall it's better than the microwave kind. My contractor says this is just soso. Regret I didn't buy the Chinese brand.
