I don't know if the Audiotop is similar to the Mr. Clean Magic Eraser or not. But $2 worth of MCME will make a lifetime supply of stylus cleaners for you and your 50 closest friends. That's pretty tough to beat.
A search here and on VA will turn up dozens if not hundreds of pleased MCME users. I'm not aware of anyone who's tried it and been unhappy.
I can buy a lot of good music for $80. To me, spending that much on a stylus cleaner would seem like spending money just to spend money.
