The base is very good without needing to assemble it easily with a straight or Phillips screwdriver. I just want to emphasize that personally I did not put the wood that connects the other two woods internally and the reason is because it would obstruct the amplifier that you see. As you can see, the base can comfortably accommodate an amplifier or other devices with a length of 43-44cm and a height of 14-15cm, just leave a 2-3cm margin if the device has air vents. As for the negatives, I would say that it moves a little, so I put 6 adhesive feet of 3M.
