There is nothing wrong with the device, it was just more of an impulse buy and I decided too late (to return it) that it wasn't for me. It's still really cool though and the same sensor can be used for golf and baseball, you just need to buy the mounting pieces separately. All parts that came with the device are included: sensor, charging cable, literature, and 2 mounting pieces (the one that uses that tape is UNUSED per the picture).
