Product review (4 stars): Very functional, great price.
I wanted a hood vent that didn't look as plain as the brands of the shelf at the hardware store but I also didn't want to spend very much on this appliance purchase.  With the flip down glass shield it gives it a slightly modern and customized look.  Product operates well.  No instructions in my box but it isn't rocket science to hang one of these.  Better for new construction than trying to retrofit into the US standard in exhaust hoods.
