Product review (1 stars): Nothing to see here...keep moving on!
Yes, I hate this product.  These magnets have no magnetic value and all three flew right off my vents when the a/c came on.  I don't get it!! Packaging looks great and talks like they are high quality but they are not.  One magnet did stay for a moment. It was kindof funny, the bottom was fluttering letting the cold air out, then the top finally released and it landed in the middle of the floor.  This is with my Carrier A/C fan set  on the low position!!  I'm looking for a set with much better magnetic hold.
