Product review (3 stars): Correct Product?  Difficult Installation!
First, this is NOT the Professional Series product "Pro Series" as described.  Just look at the instruction manual to see that the product sent is not the Professional Series range hood as identified and described by the manufacturer in this manual.  Amazon is not selling the product it is claiming!  Or Amazon's supplier is not sending the product Amazon is describing!
Second, the directions for installation that come with the range hood are so abbreviated as to be almost worthless.  For example, there is nothing on making the electrical connections, which in my case required drilling holes in the frame and removing the internal power cord connections and reconnecting after reinserting the power cord from the non-plug end - not easy at all!
Next, just try to get the upper support bar located at the ceiling level and insert the screws - any Beta testing would make it obvious that this bar should be located lower on the wall with holes to match in the vented cover section.
Then consider that the provided plastic vent pipe is not designed to fit to standard 6" metal vent pipe or vent outlets - so it has to be scrapped and replaced with metal pipe which is very difficult to fit to the fan motor outlet.
These are a few of the frustrations I had with this product.
I have a lot of experience with building renovation, and while this vent is attractive and attractively priced, it is unnecessarily difficult to install.  It requires a significant independent learning curve, which I will probably never have to utilize again!
Once installed, the range hood works fine; but getting there is nightmarish - and I am no novice!
