Product review (5 stars): Stop shopping, and buy this range hood RIGHT NOW.
If you are reading this, and have a need for an under cabinet, 30" wide, 6" round ducted range hood, pause now, click on the "Add to Cart" button and then come back and read the rest. When you're done, you're going to buy this. Seriously. If I could give it more than 5 stars, I would.

I cook a lot. We have a 900 square foot kitchen, and my family has muddled through the last 10 years with a 250 CFM Kenmore range hood.  I am overwhelmingly impressed with the BV Range Hood. This sucker (see what I did there?) far outperforms my previous range hood, and probably any other that I have ever experienced at anyone's house, in my entire over-four-decades life.

PROS:
It's powerful!
The smell of cooking bacon used to linger in our house for 3 to 4 days.  We'd be opening the windows, using fans, our prior range hood, etc. The first day after we bought it, I made bacon.  I kept the windows closed in our kitchen, and ran the range hood. I was prepared to run the stopwatch on my phone to see how long it would take to suck the smell out. I didn't do that. Because I there was NO BACON SMELL IN THE ROOM. Since then, I have made Chinese stirfry, fried cod, my wife has baked cookies, we've burnt pizza, and none of those smells have lingered at all. My children used to joke that "Dinner's ready when the smoke alarm goes off". They have not made that joke a single time, with this range hood.

It's pretty quiet!
There are three settings. On the lowest setting, I can have a normal conversation with someone sitting next to me. On the highest setting, I do have to raise my voice, but it's comparable to my prior range hood.

It's super easy to use!
Five buttons. One button for a light. Three buttons, one for each level of fan speed. And a fifth button to turn it off. Tapping the off button also runs the fan for another minute, and then automatically shuts off.

It's easy to clean!
I am baffled (see what I did there?) why anyone would want a range hood that has those cottony-insulation looking filters, or aluminum filters that you have to replace. These stainless steel baffles are dishwasher safe, and the best part, is that they are the entire cooking-facing surface of the hood. So underneath, it's not like there is a section of hood that you have to reach under and wash with a sponge. No need. The entire bottom is occupied by the removable baffles, and a trough that runs the entire 30" length of the hood, which is mis-named as the "oil drain cup". It's a trough, and it's awesome. Easily removable, easily cleaned.

CONS:
The two built in LED lights are more blue than I prefer. I generally like warmer color hues.

And that's it.

There is no reason to shop around. Buy this. Now.
