Query: Keeping our VCR alive

Our son, like many, likes to watch movies over and over again. I know how hard it is on a VCR to rewind over and over again, and to put a dusty tape in the VCR may mean doom for the tape and player. I could no longer find these cleaners in any store, so I bought them here. We are down to our last VCR, but these cleaners have added time onto it and two other used devices. They do just what they say they will, and just when I think the VCR has had it, after a cleaning, it is working again!
