misleading description, picture says with shock, waterproof, but it come without shock (my bad, I did not notice), and it is not waterproof, no seal between pieces, I opened it, be carefull befor buy, not like me. Barking senzor starts vibration only on highest level 7, but with this sensitivity vibration starts also when dog makes some moves. 1-6 sensitivity is not working. This is unuseable. Maybe bad piece?
As in picture
