Received and installed quickly. The supports are of high quality and aesthetics is much better than what I expected to receive. Once installed, the product with the speakers is very discreet. The only disadvantage is unable to rotate the main support race but by buying it I knew it was not possible therefore not a fault, it's just a wish! For the rest nothing wrong, everything is delivered to ankles and that is rare screws that gives confidence to the final strength. My 9kg pregnant risk nothing, good maintenance only by jaws (fixing screws not installed speaker) I do not want to damage the wood cabinet.
