My hand-held transmitter is still functioning, but this plastic part was torn. Then I thought, heck, just because of this little plastic part much money to spend on a new remote control ... out of curiosity, I made the radio microphone on (according to the motto: now I can make nothing more worse :-) and lo and behold, I was already against the remaining in the rest of the housing. Then I gegoggelt and Amazon found the hand-held transmitter and bought in the Amazon proposals what other customers so have this wonderful replacement part. For little money, used fast and everything works as before. Prima! From me gäbs 10 stars, but Amazon has not so much. Thanks Amazon (was again surprised what is available here) and thanks for thinking along Cobra.
