Isolate It: Sorbothane Vibration Isolation Circular Disc Pad .5" Thick x 2.25" Dia. 50 Duro - 4 Pack

I use eight of these and a nylon cutting board under my Pioneer PL-50 turntable. This turntable is large and quite heavy. These have completely cut any physical vibration from the speakers or floor from affecting my music.

My bass came alive. Perfect.

Got these to put under a concrete paver, atop which sits my 3D printer. No complaints from the downstairs neighbor in my thin-walled apartment.

Pucks seem to be decently well made. I will do a before and after with the washer and update this review later.

I use the 4-pack to diminish the vibrations from my 3-D printer. Works great!

I bought three sets of these which cost a pretty penny, overpriced for sure. But, I wanted to stop humming on my turntable and also make my audio sound better. Giving them 3 out of five stars for 3 reasons: 1: Overpriced - maybe they cost a lot to make, but I doubt $25 a set worth. 2: One set completely fell apart under weight, the weight is under the amount approved. Wasted money on those. They got completely destroyed and it was only after having them for a week or two so should have returned, but something about returning crumbles feels wrong. 3. Leave residue on whatever they are on top of. Not even with a ton of weight, the ones under my turntable left a bad amount of the material behind. I have to cut round pieces of paper and keep them under each circle. All in all, I should have went a different route. If they were cheaper I would have been less bothered, but I spent about $70 on the three sets, which I should have known better anyways.

It worked to stop phono from skipping on records, an inexpensive solution to a vexing problem!

I don't know what happened but the pucks I received had partly melted together or chemically destabilized or something because they were crumbling to pieces.

The pucks were very soft and I wish I had bought the firmer option.
