I added this to one of my USB hub output that is also used for my external HD and SSD drives for my iMac. Two weeks ago suddenly my SSD got corrupted. I ended up having to buy a disk recovery tool and didn''t think too much about it. But occasionally my disks were disconnecting and today my 3TB hard drive went down and I had to recover it (luckily nothing lost). I now realize this gadget has a flaw. There are no capacitors or filters on the USB power and you should avoid sharing it with anything data critical. You might be lucky, but it''s better to keep this powered by a separate power supply. If you want to share the USB power with anything critical, you can try to add the capacitor that should have been on this product to begin with. I added a 220uF 16V electrolytic capacitor on the rear side across the GND and VCC of the microphone connector.

Having dead space inside the Thermaltake Tower 900, I installed 2 of these were the water reservoirs go. I still need to do another mod, I just don''t know if I want them to the inside by the drive bays or outside by the glass. These light up bright and are quite colorful. Typically an easy install, plug the audio splitter adapter into your speaker output, then plug your speakers and the cable for the tower. Plug the other cable into a USB port for power. The two cables merge into one that plugs into the tower. Turn on the power switch and adjust the volume to make them light up.
