Review on 🐶 Dr.Trainer B1s Dog Bark Collar with APP Control | Waterproof Training Collar | 3 Modes (Vibration/ Beep/ Shock) | Adjustable 0-99 Static Level | Rechargeable Dog Barking Collar by Emily Mason

Simple and clear. it's not worth the money! Unless your dog has a really loud bark with a bit of bass, this device is useless. He says the lowest barking noise he picks up is around 60 decibels (about the average of two people having a normal conversation without loud conversations). A large dog's bark can reach around 80 dB or more. This device will NEVER record sound. And it will NOT work if you are too far away with bluetooth. So don't try to use it when you are on the opposite side of the house from your pet. Like I said, this is a VERY USELESS COLLAR.
