am totally thrilled by the distributor. Four computers and four peripherals connected. As a musician, stuck with me off USB mixer, printer, USB MIDI interface, USB Hub and all three Macs (or PCs) of switched by pressing a button. Two green and two red LEDs indicate which compiler is just boss. After switching the external devices are detected immediately by the other computer. The cables are long enough. The annoying Umsteckerei thing of the past. Highly recommended !
