Query: Frustrating

I bought this product because it looked like it would be easy to install and would work well being a 1 hp and it had a lifetime warranty. I have tried to install this product and haven't finished yet as it is leaking. This sink flange is tight and water is not leaking from there. The rubber gasket is on the discharge tube and it is as tight as I can make it. I put paper towels around both the flange and the discharge tube and it doesn't seem to be leaking from from either of these parts. It leaks when a lot of water is released and it drains a lot at once. I have tried everything to fix it and probably spent over 20 hours. I have an authorized plumber from the company who will come over, but he needs to get a new disposer sent and it will be another week. I thought this was going to take 2 hours max, but it was more of a month long project for me. I suspect I was sold a defective unit which caused me to waste a lot of my time.
