It was well made for its intended purpose, but I didn't need it, so I returned it. I also ordered a 3 1/4 in X 10 in rectangular to 5 in round adaptor, to connect a microwave oven/hood to a round stove hood duct. It had a 3 in long straight section at the rectangular end that cleared the top of a microwave oven/hood, so the starting collar was not required. Earlier I bought different items for this project, but contractors made changes, so I also returned them. I try to avoid situations like this, but was very pleased with Home Depot's return policy and friendly service.
