Very poor quality, wobbles at each of the joints, lower legs/tube, tube, seat to tube. During the year I used this, this only got worse. Could not fix this, as just poor construction. The larger seat is not even really that comfy (compared to Gibraltar moto-style seat).
I bought a Pearl D-790 to replace it, so much better. I probably will throw the Millenium seat away (would not even want to leave it behind in a practice room for something else to take, it is that bad).
