I ordered this stand from Thomann, along with some headphones and other bits and pieces. Everything else in the order arrived perfect, but the stand arrived with substantial rust on the joint that actually holds the piano. Not good!
I emailed Thomann and they quickly arranged a return. Once they had received the return (took a while with everything going on right now) they then sent out a replacement via courier - excellent!
Unfortunately, the second one arrived, SAME PROBLEM! The joint on the arms that actually hold the piano is still covered in rust. Not only that, but there are already small areas of chipped paint and some scratches where the stand had obviously been (wrongly) assembled before I opened it.
All in all, terrible quality. My €30 "fun generation" keyboard-stand is much better quality and never let me down. Unfortunately I gave that away when I ordered this one!
I wouldn't trust this stand at all with my expensive piano -- bizarre because it's the "official" stand for my Korg piano.
Side-note: my Korg Piano also arrived all bashed up, absolutely destroyed, keys hanging off, and I needed a replacement. What is going on with this manufacturer?!
