Product review (4 stars): a) Amazon's amazing returns policy gives me peace of mind
I was skeptical about purchasing this insert sight-unseen, due to the many reviews regarding loudness and shipping damage.  In the end I decided to go ahead with the purchase because:
a) Amazon's amazing returns policy gives me peace of mind.
b) Other 1200CFM hood inserts are twice as expensive.
c) I'm handy enough to resolve minor issues that others have reported.

I've had it installed for about 6 months now.  It definitely surpassed my expectations for such a budget-friendly unit.

My unit did arrive with loose hardware on the fan brackets.  This was a common complaint in the reviews I read, so I knew to expect it. Prior to installing the hood insert, I loosened and applied loctite to all the fasteners I could find.  Hopefully this will help prevent them from loosening while in use.

The (twin) blowers are a bit on the loud side, as many other reviewers have pointed out, especially at settings 3 and 4.  But I don't think the noise level is unreasonable considering the price point.  I figure if it becomes unbearable, I can remove the blowers from the hood and do a remote setup in the attic.  But the majority of my cooking is done with the the fan on the lowest setting.

The dishwasher-safe baffles are very convenient.  They come out and go back in without any hassle.

The position of the control pane on the underside of the insert (facing the cook top) was a little annoying at first, as I am 6'1" and have to bend over to see them.  However, after a few weeks, I began to get a feel for where they are and now longer have to look every time.  My wife is a bit shorter than me, and has no problem seeing and reaching the controls.

The halogen lights are very bright, and get pretty hot when left on.  I like that when the 3-minute timer is activated, it turns of the lights as well as the blower.

Overall, I am happy with this insert.  Only time will tell how long it will hold up.  I would buy it again for any future kitchen remodels.
