- How long have you use it?
few months

- What is so special that you like most and least?
+ the double chain, the flexibility
the -: not found but I will try, I promise

- Have you tried many other models before buying it?
I played with a single Gibraltar pedal and double pedal Pearl belt driven to my prof. Compared to the Gibraltar I note an easier adjustment and springs silent, while those of Gibraltar squeak. Compared to the Pearl with my teacher ... difficult to judge. It seems at least as well.

- How would you rate the quality / price?
Excellent and yet I am far from being a fan of Millennium products

- With experience, you do again this choice? ...
No problem. Remains to be seen how this stuff is getting older. That may be where the bottom will hurt. We'll see.
For the rest I managed to set both pedals to obtain a regular flow fairly quickly.
