dog training collar 800M remote rechargeable and waterproof dog trainer

Worked perfectly. I was getting 2 hours of sleep since the dogs moved in. One dog barked throughout the night is now quiet after the first night. Used the shock only a few times at a low setting and now just use the vibration and beep. Battery life is great. Bought it about 3 weeks ago and it only used one bar so far. Very happy and sleeping great :0)
