Decksaver products are slighlty on the expensive side, but I don't leave any of my devices without one. This particular cover is well designed to protect all the control elements - knobs, encoders and pads. The plastic is sturdy and withstands nontrivial amount of pressure. It certainly doesn't break easily - in my experience not even on large synths. I'm using about 7-8 Decksavers now and none broke so far. I use them to protect my equipment from mechanical damage or wear of control elements during transport as well as against dust or spillage. The only downside I can think of is the fact that not all of my equipment has a corresponding Decksaver, but big thanks to Thomann for bringing to Europe all the Decksavers not available to purchase in stores in my country.
