Product review (4 stars): Extremely effective hood, somewhat challenging installation
First, regarding the hood itself:
This hood has an amazing capacity for moving air, especially compared to our old microwave/hood combination. Our previous hood was rated at 200cfm and the Zephyr Typhoon is rated at 850cfm. The Typhoon is magnitudes better at moving air out of the kitchen.

Aesthetically it is very nice. We have the white hood, which I was unable to find any pictures of before ordering. It turns out that the control panel is primarily gray (not black as see on the stainless model). This was perfect for us because our range happens to also be white with gray plastic bits.

The sound level is quieter than our old microwave hood up to about the 4th fan speed setting. The 5th and 6th settings justify the name Typhoon both in the amount of air moved and the sound.

Regarding the installation:
It is somewhat difficult. There is no template for installing screws. You are just given measurements from the center of the cabinet where to install the 4 screws. That turned out not to be that challenging, but I did test-fit the hood and mark the holes with a pencil before installing the screws in the cabinet, just to be sure.

Once the screws are installed you then are directed to lift the hood up into position so the screw heads pass through key-holes in the top of the hood, then sliding the hood back allows it to rest on the narrow part of the key-holes while you tighten the screws. The challenging part is tightening those screws once the hood is in place. The alignment of the holes versus the fans in the cabinet make correctly ligning up a screwdriver basically impossible. If I were doing it again and going to use their recommended installation method I would get some hex-head screws so I could use a ratchet or wrench instead of a screwdriver.

My Ikea cabinets happen to have a joint within 1/8" of the screw locations, so I decided to augment the recommended installation by dilling through the adjacent cabinet's shelf-peg holes into the hood, and installing 4 bolts. This seems to me to be a sturdier and a much easier means of installation, if you have someone to help you hold up the hood while you drill.
