Just something for optimists

I had already had a cassette adapter, which was powered by batteries. This meant that he had torn me a valuable Cassette. Wanted to try with this mechanical part of it now. After a bit more careful handwork I managed the first cassette. But already at the 2nd hooked it. When I tried with the 3rd was already wedged the tape and also to bring the mechanics again only with difficulty apart. Will not risk adapter landed immediately in the trash. If anyone knows an adapter for me which is reliable, I would be very grateful for the tip.
