When I first received the item I was disappointed that the audio quality was fairly weak. The subwoofer was okay, but the main speakers really can't handle much sound.
Also, the photo and description are very deceiving when it comes to the "sleek, flat-panel left and right speakers, as well as the main unit, are wall mountable, enabling you to save valuable desk or shelf space."
I chose this thinking that I would be able to flush wall-mount very thin speakers and the main unit. What isn't revealed is there is a pretty chunky box hiding in the back of these units: these aren't flat panels, at all, really.
Lastly, I too, feel burned by the remanufactured quality. The remote control sensor went dead after about a year of use. The second biggest reason I purchased it was so I could control it via the remote while working out. Now it's next to worthless for me.
