Product review (3 stars): Very Good Value But May Need Tuning
This review is for the 36" model.

Just received our fan and wanted to post some initial observations. I will update this review as I learn more.

As background, I bought this fan mostly for power and value. And this fan seemed to be a good fit for my use case (needed a slim housing less than 5" tall)

The packaging was adequate, and everything looks to be in good condition.

The housing truly is 4" tall. The fan covers, etc, will add to this, but overall, this fan can be called "slim". The housing is at most 35 1/2" wide, so it looks like I'll have 1/4" gaps on either side.

The housing comes with a 6" hole on top and a plastic duct connector with gravity back draft flaps. Will have to buy a 6" to 7" adapter at the local hardware store.

There are four screw holes in the sheet metal top for under-cabinet mounting. There are also two brackets included for mounting without a cabinet. The screws included (two "expanding sleeve screws and three sheet metal screws with anchors) don't seem like enough, so expect a trip to the hardware store.

The light bulb is a funny looking incandescent with a common E27 base. I think it's a halogen. The color is nice bright white with good color rendering (will be nice for seeing food clearly). But the lamp gets hot quickly. The housing has a sticker that says rated for 40W max. Remains to be seen if I keep this or replace with an LED that can handle some above-the-stove heat..

Everything tested OK electrically. Testing the fans, there was noticeable vibration; one was pretty bad, the other was worse, and not acceptable.  Taking the fan blade off the "worse" side, the motor shaft itself seems to not be the problem. So I'm left thinking the fan unit (metal) is unbalanced, or the plastic shaft caps (mentioned by another reviewer) are adding vibration. I'm going to do some more testing. I can't imagine this not being fixable somehow. The fan already has one balancing clip/weight. It may simply need more.

The design of this range hood is very minimalist. I mean that in a good way. The electronics are very simple and appear to be pretty user-serviceable from the bottom, which is great for something I want to install once and not have to remove again.

That's all for now. So far, based on the price, shipping condition, design and power, I'd give it five stars. But I'm knocking off a couple until I figure out the vibration issue.
