Product review (3 stars): Good QualityYou'll Need Several Add-ons To Install
An absolute nightmare to install.

Thing is, you need some additional items to install this hood (Broan 423001) and this list is neither included in the Product Description, nor the From the Manufacturer notes just below the description. However very near the bottom, beyond the point of being tired reading that stuff are the words, "BP87 dampers sold separately." Yes, it is AND YOU WILL NEED IT.

The List of What Need/Must Have To Install:
1-BP87 damper
1- 7" to 5" reducer as 5" is likely the diameter of your ducting (DO CHECK THE DIAMETER OF YOUR DUCTING). If you don't use this, return it.
1-Roll high temperature flue tape. The smallest roll I found was 5 yds long by about 2" wide. It is NOT DUCT TAPE.
The cost of these items ran about $40 more than the cost of the hood, so plan this into your cost of installing. If you don't have the correct tools such as the short list below, add still another $40 to the total cost. I got my range hood when the price dropped to around forty bucks, and with all the extras, my end cost came to just over $85.

As for tools, you'll need at least and hopefully you've got these already:
**Set of open-end wrenches (spanners for you Brits)
**3 or 4 electrical nuts to connect the fan and light wiring. Remember to GROUND THIS HOOD as spark in a grease flue can cause a fire. (most all range hoods collect grease in the filter and inside the ducting).
**Various smallish flat- and philips-head screw drivers
**A good, bright flashlight (torch for you Brits)
**Some electrical tape as you may need it. Wish I could be more specific about that.
**A great deal of patience

Some final thoughts
Get the space where the ducting runs open and accessible BEFORE starting.
SHUT DOWN YOUR COMPUTERS AND PRINTERS then you can TURN OFF THE BREAKER supplying power to your present range hood. Household wiring is, at times, illogical and the power for the range hood could be on the same circuit as the home electronics. So shutting down your computers is a safety step to protect them from the power surge when you turn the power back on.

If the manufacturer had listed these add-on or gather together list, it would have saved me a couple hours frustration while driving around looking for the Need/Must Have stuff, it would have been much appreciated. The list under discussion is printed inside the manual that ships with the unit and while that's okay, I'd have preferred to be doing all the purchasing of these items so I could have been installing when the package arrived.

Quality:
This range hood is made with what seems to be high quality material. The finish is even on all the surfaces. Dimensions are correct and as described. The front panel switches have a solid, quality feel when turned on and off. I rated the item 3-stars for not making the list of necessary additional items clear and complete in the Notes From The Manufacturer on the page with the item's listing.
