It really fits the Korg Kronos 88. It is a bit heavy, which, combined with the already significant weight of the Kronos, makes it quite cumbersome. However, the wheels and the two transversal handles provide assistance and allow for help from others.
I have just received it, and I hope it lasts for many years.
I had some issues with the first one I bought, as it arrived without the side handle and with the inner foam rubber slightly unstuck. However, the team at Thomann replaced it without any problems
