Product review (3 stars): Some Features Disappoint
The image appears to be that of either the 30" or 36" dual-blower, under-cabinet range hood made by Electrolux. I recently installed the 36" inch version (model RH36WC40GS). Removal of the protective film on the hood's body and grease filters was tedious and time-consuming. Hard pounding with hammer/screwdriver was required to knock out the vertical duct openings for installation of 7" round duct. I was afraid that the pounding might have damaged some of the hood's electronic or mechanical components, but luckily that was not the case. The installation guide designates an incorrect location for the hole to be drilled in the cabinet bottom for electric-cable access.

The electrical connection (hot, neutral, and ground wires) must be made inside a plastic box that is too small. The work-arounds required to compensate for the small box depend on the particulars of the installation. In my case, I decided to insert a mere plastic shield into the access hole in the range top (rather than a cable clamp) and to create a cable-clamp at the two-inch-diameter hole I'd drilled in the cabinet's bottom shelf.

Installation of light bulbs with the required GU10 base was difficult because the light bulb blocks your vision of the two holes in the receptacle into which the two prongs on the bulb's base must fit. And, the only way to twist the bulb into its final resting place is to use some device, like double sticky-back tape on the bulb face, to get enough friction to twist the bulb.

The grease filter attachment is also user-unfriendly. There is no supporting ledge along the base of the range hood, front or back. Each filter's frame has two fixed tabs on the back that must fit into slots in the back wall of the hood (can be tricky). There is a spring-loaded handle near each filter's front edge which operates two movable (in-out) tabs on the frame's front edge. The handle must be held open to retract these tabs until proper alignment of the filter's front edge is obtained. Then the handle is released and the two front tabs pop out unto slots in the front wall of the hood. Care must be taken when removing a grease filter so that it does not fall onto your stove top. As you open the handle to release the filter's front edge, you should keep your other hand under the central part of the filter, because the filter will fall out of the back slots.

The LCD display is almost useless. Unless you are a really short person, you will have to stoop to make the displayed characters visible. This is an extraordinary shortcoming for a range hood that is this expensive and can only be tolerated because the display is not essential. The range light must be on or off.... no intermediate light levels. To use the highest (fourth) blower speed, you must punch the "up" button four times. Then, to turn off the blower you must punch the "down" button four times (my previous, less expensive Broan range hood had an on/off button for each of its three speeds... plus three on/off buttons for three different light levels).

Once the range hood is installed, and you are satisfied with the single light level and button-push logic, you are happy to find that the blowers are not too noisy (air-wise) and that the hood does a good job of ventilating your cooking. For me, however, there remains one significant complaint: The magnetic hum (120 Hertz) of the blower motors is a bit harsh. Now, many... maybe most people won't notice or be bothered by this hum. Electrolux says that the hum is normal. However, many fans and blowers use what is called a "permanent-split capacitor A.C. inductance motor". These are relatively inexpensive motors, and it is possible to design such motors so that the magnetic hum is negligible. I don't know what kind of motors this Electrolux hood uses. I do know that the blower motor in my previous Broan range hood had a somewhat quieter, softer hum than these motors in the Electrolux hood.

The build quality of this range hood is very good, and it has an attractive appearance. However, because of the negative factors mentioned above, and because of the high cost of the hood, I would not recommend this hood to a friend. And, believe me, I wanted to like this hood, having just un-installed the old Broan hood, installed 7" round ductwork to vent through kitchen cabinets out to a screened-porch wall, re-installed the Broan hood, decided to buy a new hood, un-installed the Broan hood again, and installed the Electrolux hood. That ain't easy for a retired 75-year-old engineer.
