The Thon Keyboard Case for the PSR-SX700/SX900 models impresses with its quality and surprisingly light weight for its size, making it a solid choice for musicians on the move. However, while the case is generally well-constructed, the finishing touches leave something to be desired. I encountered issues with sharp edges on the case that ended up damaging my car seat during transport, which was quite disappointing. This oversight in the finish could be a concern for those looking to keep their gear and vehicle in pristine condition.
