Every person I've seen that has posted, has had nothing but positive things to say. But you kind of expect that about something you've spent so much money on. :) Whether they're worth the money is, IMO, kind of a tough call. If you plan to keep the trailer for 10 years or more, and travel many miles, and you don't mind spending the money, then it might not be an issue for you.
I got rid of the poor Lippert EquaFlex equalizers and installed the EZ-Flex from Dexter, and heavier rated springs. To me the trailer rides very well, but it's all pretty subjective.
OTOH, I doubt that there's any question about the performance of the disc brakes. That strictly boils down to "Do I want to spend the money?".
