These are great additions to any studio.
Combined with the humidity in our atmosphere, dust is literally a killer. Anything with faders, pots or switches will thank you in the long run for this type of protection. We spend so much on these musical gadgets that adding a few quid more simply makes sense. Some of these synths etc.. have certain types of rubber in their pads & buttons, that attracts dust. If you are not using something for a while decksavers are a no brainer really. Its far easier to prevent problems than pull things apart & clean out grime / replace parts.
They are very strong. Good quality. I did some research before I went for the decksaver brand & chose them as they weighed the heaviest, which in my mind equaled quality & durability in normal everyday use. Not disappointed. The Launchcontrol XL is a brilliant controller btw.. if anyone was considering it. Teams up very nicely with Push 2.
Nothing to criticise here. People might think its a bit over the top getting these items.. as it adds to the total spend & budget might be tight, but I can honestly recommend it.
