It worked as advertized.Before using it, I looked it over carefully. The mechanism seemed to be sticking a little bit, so I sprayed everything with a silicone spray dry lubricant. This seemed to make it open and close much smoother. Only then did I insert a tape into the adapter.I inserted the VHS-C tape very carefully, making sure that it was positioned just right before closing the adapter. Then I inserted it into the VCR just like a regular cassette. It worked the first time. I was very pleased.I can see that the adapter is dellicate and should be used carefully. But that said, I did not have any problems.
