Review on MAISOIE Electric Dog Training Collar - 1300ft Remote Range, 3 Modes: Beep, Vibration, Shock - IPX7 Waterproof, Rechargeable - Ideal for Small, Medium, Large Dogs by Edgar Vasquez

I have never used a training collar before but the 8 month old lab puppy we got from a neighbor got out of control. Immediately difference in behavior. There was no need to shock her, mainly with the help of beeps, occasionally with vibrations. People comment on how far she's come in just a week. The only minuses are problems with the design of the remote control. I wear it on my belt and the antenna is taped to my shirt. Also, the clip doesn't hold up well. The remote control falls during elementary movements and needs to be moved frequently. BUT definitely worth the money.
