Product review (4 stars): A good deal overall
After scouring the internet for a good deal on a kitchen island hood, I chose this one based on price and previous reviewers.  Overall, I am very pleased with the results.

I inspected the hood once I got it in case it was dented as others had pointed out.  I thought it was packaged nicely.  Instructions are downright comical with some of the obvious Chinese to English translations.  And everything is in millimeters.  No big deal really, but you have to double read everything and then look at the comic like illustrations to get the idea.

For sure, DO NOT use the "rubber expanders" (thats how the instructions call it) to hang this right from the sheetrock as suggested by the instruction.  Molly, toggle bolts, whatever you want to call them, you simply cannot hang 65+ pounds vertically from sheetrock.  As others have suggested, you need to build a box of 2x4s off of the ceiling joists and attach the hood mounting plate DIRECTLY to wood.

I found it strange that its powered by a 3 prong cord and not hard wired since its a permanent fixture.  I mounted mine to an 8 foot ceiling by myself by basically winching it up with a rope and then locking it in place.  My hood is about 27" above my cooktop.  This leaves the 3 prong plug about 8-10 inches past the ceiling.  I then had to install a single use outlet box just for this to plug into.

The lights on it don't really do much other than enhance existing lighting in your kitchen.  I am actually able to use them as a nightlight in my kitchen dining room area, that's how dim they really are.

The 3 fan speed work great.  I fried onions last night and not a whiff of it in the house.  My wife was outside and came in to tell me how wonderful the neighborhood smelled now.  So its working for sure in that aspect.

Sound at highest speed is not too bad.  I can still watch and hear the TV in my dining room if I turn it up a little bit.  You can still easily have a conversation.  I have found using it on 1 or 2 setting to work just find and clear things out.

The military grade 24hour clock is nice and bright.  If anybody can figure out how to put it in 12 hour time, that would be great.  Luckily, I have 2 other clocks in my kitchen, so not a big deal.

Instructions need to be clearer, but I think any good skilled DIY person can put this up in an afternoon.  I did it by myself in about 4 hours.  One thing that slowed me down is that its a 6" duct system.  Lowes and Home Depot in my areas only carry 4" duct and roof collars.  So I could not cut the hole in my roof and vent it until I ordered a 6" duct system from Amazon (Speedi-Products EX-RCGC 06 6 inch).  Was only $30 and it works perfectly.
