Review on PaiPaitek PD-258s Electronic Collar, Collar Length 66cm, Neck Circumference 12-55cm, 1 Piece, Black/Silver, S by Micha Gozdalik ᠌

The collar was worn according to the instructions. The device itself is in order, if you blow into the sensor according to the instructions, then it works. But for a very loud, sonorous barking of a medium-sized dog, when it is put on (I tried it with different lengths of electrodes and with different degrees of strap adjustment) or even if you bring it directly to the mouth during barking, it does not work. But it works from scratching. But the seller put a gift to the order (a metal whistle), the whistle is cool, it works.
