No going back for me. It may be a case of YMMV but for my table it improves the contact with the platter, regardless of record, and seems like the last piece of the turntable setup puzzle for me. I also find it super easy to use.

Anyone have any reason to NOT give this a try (besides the price)? Or anyone recommend an alternative? I have great weights/clamps/mats but definitely own a few thousand less-than-absolutely-flat records, and feel like it’s a shame to be missing contact.
