Product review (4 stars): All good in the hood!
I purchased this product feeling I was taking a bit of a gamble since comparable performance in better known brands is about twice the price.

When the unit arrived I quickly unpacked it and plugged it in to see how it worked since I didn't have a good idea of what Sones and CFM actually sounded and felt like.  I can tell you that 1200CFM is a lot of air movement, it cooled my whole house down after running for a couple of minutes.  The sound you hear is air too and not motor sound so the way I see that it is as quiet as can be.  The only thing that could make it quieter might be engineering the airflow differently.

Unfortunately on the lowest speed settings I could here the fan rubbing against something internally.  I called the company and they noted the condition but asked me to poke around and see if there was something that was dented or came loose during shipping.  I said that there were some dents and a loose screw rattling around in the enclosure.  Most of the construction is riveted so not a lot can be taken apart and put back together.  I think each fan comes out as a unit but cannot be disassembled itself most likely (I didn't want to try and end up damaging anything myself).  They sent a fedex pickup to get the defective unit and shipped out a new one.  The new one has no rattle and works fine after a quick test.  the outside of the housing is still dented a bit in the same location but it is in an area that will be enclosed and not seen.  I think this is a design/tolerance issue with the manufacturer.  I was a little perturbed that I was asked to actually see if I could "fix" a defective product and wasn't offered a discount or anything, but it wasn't that big of a deal.

The unit seems like it is built cheap, but also strong.  The lady on the phone said that in all her years at the company they had only had one warrantied motor replacement and that it was probably the owners fault due to inadequate lightning protection or something.  The part of the unit that will be seen is very nice.  The lights are very bright as well.  I'm not sure how easy they will be to replace though.  I kinda wish there were different light settings since they are so bright.  I am slightly concerned with the amount of electronics inside the unit.  It's just more stuff that can potentially break, but only time will tell.  The time delay feature seems like it could be nice since we often like to leave the range on immediately after cooking, but don't need it on during the entire meal.

Hope my review was helpful.  I thought I would be as thorough as possible since there are no reviews on this product.  All in all, buy it!
