Product review (4 stars): easy to install
when you try to install, you will have to kind of force the metal flange over the the end that connects to the garbuerator, then fit the black rubber gasket and it is ready to connect. For the other end thats hooks to the drain pipe I had to use a different gasket than the one provided(white colour).The gasket I used for the drain end has a bit of an angle and can slide over the pipe to form a good seal once you hand tighten the plastic nut connector. This tube was easy to install and saved me the big hassle of having to re-do all the plastic drain pipes to have them aligned properly. The thickness of the tube seems a bit on the thin side but time will tell if it leaks. I highly recommend this product.
Its been over 9 years since installing and no problems
