It does the job yes but I question the "double bubble" design instead of a flat surface. It makes the plastic come scarily close to the tonearm if you leave it on while playing.
Another lost opportunity is the fact that you can't attach the original hinges on this. Such an obvious thing to do, and it really impacts the usability of this item.
I have a bunch of decksavers for various gear and am happy with most of them, but they could have thought this one through a little bit better.
