[Jo21]

i have owned 4 dual shocks controllers.
1 ps2 came with the console after 5 years still works as new
and never had problem with them.

3 second dual shock 2 no problems

only have less than than a year with the sixaxis since dec 2007

and dualshock 3 since june after metal gear solid 4 release.
