Dog Training Collar with Wireless Remote Rechargeable 300M

I have bought this vibration remote training collar for my dog, and it works great for alerting her attention. I started at the medium setting with vibration to train her and only a few days her bad behavior change a lot. Moreover, I received customer services Email from the seller about the product’s video on how to use the dog training collar. It helps me more easy to set up a remote collar. I am also satisfied with the charger to both the remote and the collar at the same time and it is convenient.
