Product review (4 stars): Its really good but I wish the lowest setting was even lower.
3 or 4 month update:  I'm still very happy with this hood and it sucks up nearly all heat, smoke, and steam, especially when using the back burners.  Cooking smells lingering upstairs have definitely been reduced compared to the microwave.  I am taking the rating down to 4 stars because I believe the lowest setting should be even lower while keeping high where it is.  75% of the time I use it on low, 20% on max, and 5% on 3.  IF low were even lower then I could utilize the speed control more.

Original Review:

I just installed this hood a few days ago so the rating is based on my initial impressions.  I am coming from a OTR microwave with a very loud and ineffective hood function even though it was ducted to outside.  The Typhoon is much quieter on its lowest setting and probably more effective than the microwave was on high at the lowest setting.  My duct work probably limits the highest settings on this hood but it seems to capture most steam and smoke.  The controls work well enough but it would be nice if the light didn't turn off when the vents were turned off.  The lighting itself is awesome.

Installation was not hard if you have moderate handyman skills.  If you are a novice at handyman work then you'll do some cussing, especially if you were alone like I was.  The biggest tip I have (stolen from other zephyr hood reviews) are to throw out the screws that came with the hood and get some hex head lag screws instead.  This will make it much easier to tighten them after the hood is in place.  The second tip is to make yourself a cardboard template of the hole location.  To do this flip the hood upside down without any duct adapters on and trace out the hood along with the holes.  Tape that to the installation location and you can drill right through the template.  Finally I had to modify the rear vent duct adapter because of issues with my own house so be prepared for that.  The hood also came setup for direct wiring so I had to install a chord.  There is a nice little junction box already there to do this but you'll need to buy the chord, screw on connector things, and a wire clamp.  Total installation time including changing out top vent for the included rear vent parts, rewiring, and mounting screw installation was about 2 hours.  Messing around with my ductwork added another hour but that's not the fault of the hood.

Lastly check for any whistling before putting the bottom cover back on.  Due to the duct modifications I had made there was an annoying high pitched whistle that was fixed with a piece of aluminum tape.
