Good stuff. I take off 1 star for the lack of finish in the assembly housing. By cons, it works perfectly. I'm glad. because I had tried 3 products Hama brands, B-tech and Speaka who had all three the same defect: the sound going on speakers that were supposed to be extinct. On that one, no problem. The buttons are much more robust than the picture lets see. The whole gives the impression of strength test in time. I recommend and in addition it is very affordable. Another plus: we can see on the image he has 6 sets of terminals. This is explained by the fact that driver 4 pairs of speakers (biensure) + entry (although sure), but it also has an output to redirect to another switch or a pair of speakers supplied Direct.
