I got this to hide the 12 AWG speaker wires and power cord that my robot vacuum cleaner keeps getting tangled in. 20 dollars for it. The hole channels are too small. The 12AWG speaker wire is too thick to go through the left or right channel, leaving only the center channel. It is too small for 12AWG speaker wire + power cord. I got it working but it wasn't much fun and it took me a lot of effort to get both wires in. But guess what, my RoboVac gets stuck on it too! The beats are too high in my opinion. While the ramp is too short. I took off the stars because the duct was too small for my speaker wire, not because of an issue with the robot vacuum.
