Product review (2 stars): You get what you pay for
Bought this range hood as I read its specs saying over 800+ air flow.  I cook greasy stuff so would really like a powerful range hood to get rid of the smell and smog.  The AKDY came alright and shipping was fast.

However, it was not as powerful as the Pacair hood I used to have even if the air flow number for this one seems higher.  Turns out that the 840M3/H number in its spec was not the same as the standard air flow measure CPM other brands and model would use, so there is some level of misleading here that I really don't like.

Also, the motor was terribly noisy, even on the medium speed, not to mention high speed.

Not liking it, but since it is not sold by Amazon, would be a headache to return so I'll have to bite the bullet and keep it.  The next time I update it, which I suspect won't be long, I'll go back to the Pacair brand I have used in the past.
