Review on 🐶 Enhanced PetSpy M686B Shock Collar: Waterproof 2-Dog Trainer with Vibra, Beep & Remote Control by Kim Palmer

We purchased the PetSpy Model M686B 2 dog training collar in October 2018. We really like the layout of the control buttons on the transmitter, which makes it easy to set levels and quickly perform functions when working with 2 dogs at the same time. We have 3 Chocolate Labs and 2 younger ones need a setting adjustment from time to time. These training collars are used daily since we have them for walking or bird hunting with our dogs. The collars were exposed to heat, cold (-30°), mud and snow. and water. Battery life in the transmitter and collars is up to 1 week on a single charge when used for more than 1 hour daily. About a month ago one of the collars started to lose its resistance to shock and vibration and the dog was not responding. I emailed support@petspystore.com explaining the situation and within 3 days we received a new receiver for free. All of our dogs are watching over us now. I'm giving these 4 stars because we don't yet know how long they will last, but for now we're happy with everything. The only thing that could be improved is the discharges or clicks between the numbers to change the intensity.
