Decksaver Technics SL1200

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.

Top-notch quality and perfect fit. I can remove them very quickly when I want to work on the decks. There’s no of that wrestling to pull them off like with the original lids which often don't come off smoothly. This version of the covers suits classic vinyl DJs the best BMHO and for those who like working on "naked" decks since live sets are often recorded with the turntables uncovered. I don't get the comments saying these covers aren't working if the platter is spinning underneath. Well, obviously not as I never listen to records with the turntable lid closed anyway so this might not work for Hi-Fi enthusiasts who likely prefer the original lids and just for listening to records unlike DJ's who keep the decks uncovered as they’re actively mixing records or recording live DJ sets. The packaging doesn't look cheap and come really decent for the price. You can tell just by looking and touching the product. I was surprised by how perfectly they fit the turntable. They really exceeded my expectations. I recommend them to anyone needing high-quality turntable covers that don't cost a fortune so it's an ideal way to protect your decks against dust, bumps, falling objects from height, spills, etc.
So to cut a long story short: Perfect fit & top-notch qually. Thanks to Thomann for selling great product and expeditive shipping.

Decksavers replaced original Technics MK-2 dust covers which stud the test of time for at least 20 years.

They feel really sturdy and at the same time they are flexible which makes them hard to break. With the flat design they come really handy in tight spaces as you can safely put controllers or laptop on the top of your turntables. That was really tricky with original dust covers because of the tonearm bulb in the upper right corner.
