Good solid design. Good sensitivity, great volume. It can be easily programmed with the SMP418 / 419 encoder program. It works well with the "8 in 1 programming cable". I marked the correct connector in the picture (2.5 stereo jack connector) The program can be downloaded: https://link-4share.com/download/a3aqmv0D/smp419_en_1_0_5_zip.html
