Review on GHORA RS1 Dog Training Collar with Remote - 1200Ft Control Range, Shock Collar for Dogs 8-150lbs - 3 Modes: Beep, Vibration, Shock - Rechargeable & Waterproof E-Collar Ideal for Small, Medium, Large Dogs by Ricardo Malhotra

This collar is great! I prefer my dog to be off a leash and this collar helps him stay in control when around other dogs and when he's getting stimuli from interacting with other dogs. I use the vibration mode, which is enough for my dog. I know a lot of people are against these collars, but the vibration doesn't harm the dog at all. This gets his attention and allows me to change his behavior and direction. We live on a busy street and he was taught not to walk in the driveway. The remote control makes it very easy to control my dog remotely. The battery life is good and the size doesn't bother my dog. We've made great progress. I recommend this learning tool.
