Any one try the new Synergistic Research BLUE UEF Duplex receptacle?


Looking for comparsons to other high quality outlets.

My thoughts on the Blue from the other thread, definitely a keeper, much more dynamic and wide open than the Black, even to the extent that it can highlight problems elsewhere in the system

and grip is fine, not hard to use but firm enough, like the Black in that regard
Have 2 R1 outlets @ the wall and just got a freebeee SR Black from my PC UEF SE buy.

Is it worth installing the Black at the wall as my PC SE are all black or go Blue?

Is the R1 outdated now?
