How long have you use it?

I have used that to get an opinion on the matter.
What is the particular feature you like best and least?

To be particulire, well l. .. yes, it is particulire! I do not like the pedals: you have to take the shot ... to switch between single action double. That's it. APRS, the flat going full speed. For me, the Duallist allows those who do not double matrise conventional bypass the problem ... Unfortunately the one who, before a concert, sees his dual hs: it will be unable to repay its DBiT "duallistiques" on a traditional double, as the left foot ... Duque.

Have you tried many other models before acqurir?

Just for a test ... That's it!

How do you report qualitprix?

Bof ... I know nothing at all l. .. as Sergeant Schultz would say.

Exprience with, you will do again this choice? ...

I never n'achtereai of Duallist! I work hard and play prfre on any of the double march.
