Cartridge is extremely durable

Have put in a car radio cassette. But did not know that the cassette compartment was broken. The result was that the cartridge could not stop.
Was also with a pair of pincers gave the cassette compartment it is no longer free. We had to expand in order to get to the cassette radio. But the radio still playing and the cassette has also survived. It is true that some signs of wear, but is still running. So: Dear test before the cassette compartment with an old or empty cartridge. Otherwise, I can recommend the cassette.
