Used presto  popcorn maker  for many years.  Use it several times a week.  Makes perfect low fat popcorn every time.  Buy the big 5 pound bag of  popcorn [also on amazon] it is the perfect combination.  We are very happy with the presto paper discs and this is the only brand we use.  The popcorn seems to pop bigger and fluffier when we shake the kernels around before putting them into the popcorn maker.  You may have to experiment with the time necessary.  Each microwave heats a little differently.  We use 2 minutes 27 seconds.  We also found that where you place the popper in the microwave makes a difference in the popping.  Ours works best placed in the back left hand corner of the microwave.  If you like fresh popcorn you will truly enjoy this presto
