I bought two of these boxes to hook up multiple components to an older tv with only 2 HDMI ports. I bought one initially which was working fine, and then a second one about a month later once I needed the additional ports. I even waited several weeks before trashing the receipts, to make sure everything seemed stable.
Now, of course, the original box is non-functional. It has power, will switch inputs, but will not relay a signal from any of the 4 devices hooked to it. I did the usual testing - hooked the same components into TV, changed cables, etc - and determined it must be an issue with the box/output since everything else worked standalone.
The second box is still functional, but I didn't realize there was a problem with it until I hooked up additional components. Ports 2 and 4 seem fine and work as expected, but either 1 and 3 are mislabeled or the wiring inside is crossed. Device hooked into port 1 gets a signal on 3, and vice versa.
All in all, product seems very poorly made - despite Best Buy pushing it as superior over other brands they carry (I believe they now own Rocketfish). The price point makes this even worse. Similar devices are half the price on Amazon, and even if they work half as well, that would be a slight improvement.
