Nice, consistent thickness and perfectly sized outer diameter, center hole.

Definitely reduces static (winter in New England doesn't like vinyl), Perfect thickness, and looks great under color vinyl.

I would recommend getting the 1/8", it was the perfect thickness and fit nicely on my turntable.

the thickness alters the angle the needle is contacting the record, improves things as best I can tell.

Perfect thickness, not too thin, not too thick.
