I never understood why these devices existed back in the VHS days when pretty much every VCR in existence could rewind tapes. I thought their purpose was for if the rewind function was broken on a VCR. Today I did a little research to find out more. The Wikipedia article claims they saved wear and tear on the VCR and the tape itself. What’s your take on these devices? Did you use them? One interesting thing I came to realize in my search for these devices on eBay was that not too many reputable brands made these machines. The only big name brand I saw was Magnavox.
