Looks cool, and I know a lot of people like to heat the records up, some people between two panes of glass in the sun. Myself I would never reheat a record, and I would think that not only with a flatt n the records, but may do something to the grooves.
As an alternative, I sprung for the periphery ring, and it was hundreds of dollars for the universal one but I figured I'd only have to buy it once. Works like a charm because I was getting sick of sending back new LPs. You would think after all these years that they would be able to make a record that isn't warped upon purchase, but that's definitely something they did better back in the day. Probably all the recycled vinyl material.
