You might think you do not really need this cover but it will prove very valuable some day. It will save your equipment from dirt, dust, liquids and semi-heavy impacts. The quality of the material is not really ideal and it bends, I would like it a bit thicker. Also, it is not suitable for carrying around because it does not clip on to the S2, it just covers it. But nonetheless it is a very useful thing when you are not using your equipment, it is easy to use and an absolute must have for Kontrol S2 Mk3 owners. Do not buy S2 without that cover (it comes as a bundle with S2) unless you already have a good protective case.
