Product review (2 stars): Mediocre range hood
I purchased this range hood as a replacement for a hood whose motor had finally failed after about 55 years.  This new hood is inferior in most respects.

To start with, the construction is, if not flimsy, at least cheap.  One retaining clip for one of the light bulb sockets was broken out of the box, making the socket loose.  The old hood had a body entirely made of stainless steel; this one has stainless steel only on the surfaces that are visible when mounted, with the rest being galvanized steel.  The old hood was stiff enough for either a wall mount or an under cabinet mount; this hood requires a cabinet for support.

The grease filters look more like spatter filters; you can see through them, so I doubt they catch more than a fraction of the grease.  Because of this, disposable supplementary charcoal filters - not provided with the hood - are needed for a ductless application; replacing those will be a major increase in maintenance cost over simply washing the more robust grease traps from the old hood.

The installation instructions are pretty good, though more detail would be appreciated in places.  The alignment of the holes is good.  In addition to the charcoal filters for ductless applications, you will need to buy expensive halogen bulbs and a cable clamp, as those are also not provided with the hood.

The controls are nice.  The fan is loud on high speed, but low speed is probably adequate for most uses.  Unfortunately, the filters often rattle when the fan is on, even on low speed.  And on either speed, the hood does not draw much of the plume from the front burners, and does not even draw all of it from the back burners; the design is such that most of the air rising from the stove is directed away from the fan intake rather than toward it.

One would think that with 55 years worth of technological progress, manufacturers could provide a better product for a reasonable price.  Unfortunately, that does not appear to be the case.
