I love the convenience of a disposable cup, but sometimes you get handed a very shoddy one that tipples over at the slightest breeze. In fact recently at this out door restaurant, they served us our dinks in paper cups and just as I was half way through, the glass blew out with the wind, spilling the drink on the table. If it had the weighted option of the Cup Ring, then I guess no wind or accidental touch would dare to tip it over. So in way, though its not rocket science, Cup Ring is a practical solution to a very plausible problem.
