Product review (5 stars): Solid Fan, Solid Company!
The fan itself is very good.  The cfm # is true and it looks finished and clean in the final install.  I accidentally ordered a 36" instead of a 30" hood and that was a costly mistake.  Be absolutely sure this is the fan you want.  Be absolutely sure.  If you need to return it, you will pay dearly.  I had to pay the initial and return shipping on the 36".  This totaled roughly $170.  You will have to pay this.

Update! Pls read.  Turns out this company stands behind their product better than any I've dealt with.  Apart from the shipping mess, I am sure you will be pleased with this vent.  Had a small issue with lights.  They were replaced by the company.  Then there was a flickering.  New transformer, new lights, all sent immediately after just a quick email.  Apart from this little issue the fan is solid.  If there is an issue, RangeHood Direct Buy will correct it quickly and professionally.  Very good company!
