Product review (5 stars): Seems to work very well!
I like to keep bananas in the fridge, along with other fruits and vegetables, and I tried the Whirlpool Fresh Flow Produce Preserver in hopes that they all would keep longer.  It seems to work very well, and the bananas keep much longer!  You need the Starter Kit to hold the actual preserver packets (2), so give it a try if you are tired of mushy fruits and vegetables before you get a chance to eat them!
