I bought this soft Thomann cover for my new Behringer Pro 800 synth, as that was the cover recommended by the Thomann website. It is a very cheap material and a quite useless product. Not a tight fit. If you pull it over the synth module on one side, it slides off on the other side. This will not keep dust out, or protect against objects falling on top. Next time I’ll buy the very expensive DeckSavers hard covers again.
