Product review (5 stars): Versatile if you don't know whats under the hood
If you're on a budget and need a range hood fan, this is THE super easy, no frills, no thrills hood fan. It is one of the most versatile oven range hood fan youll find out there. Its not the prettiest, but it has one job and does it fairly well. Its quiet and just works. The ONLY thing it doesnt come with is the power cord.

The first unit was damaged to hell during shipping and Amazon quickly sent a replacement. With that said, the sheet metal that its made out of is very thin and can be bent in/out of shape fairly easy. The range hood can accommodate round and rectangle vents, or no vents. That was the main reason why I got this, because I didn't know if my current one even had a vent. Thankfully it did and fits.

The instructions are somewhat convoluted with technical jargon that will make you say, WTF did I get into!? Rest assured, its super easy and NOT complicated at all, except for power.

First detach the silver vent attached to the hood. Depending on your venting, pop out the pre-punched holes for the correct venting style. Mock up your hood to the resting place and drill or (loosely) screw in the screws to hold it in place.

Take the hood off, and get a 3-wire pig tail plug (not included) to connect your power to the hood. Luckily I hoard and have a bunch of computer power cords for this reason. Strip the power wires and you should have white, black, and green. Before attaching the plugs, punch out the correct hole on the hood for power cord placement, then stick the cable through the hole to continue. Green get grounded to the green dyed screw underneath the power box, the white goes with white, and black goes with black. I used wire nuts to secure them and then used black electrical tape to further secure them.

Place the hood back on, plug it in and make sure it works before securing the screws. At this point I noticed it wasn't that loud, even on the high setting. I can still have a conversation with it on high.

Now for the duct work, remove the power, remove the hood, and attach the new venting duct attachment onto the hood. If you have an existing hood range, simply slide the old venting duct onto the new one. Once on, now secure it with duct tape along the exposed connecting points so that smoke doesnt seep through. Now you can say you used duct tape as intended.

Hopefully this has been helpful. Good luck!
