dog training collar 800M remote rechargeable and waterproof dog trainer

This has worked perfectly for us. I only used the shock button once on accident. It was user error. It was dark and I got the wrong button. After 3 weeks and 1 user error, it’s like we have a new dog. I simply show him the remote now and he corrects his behavior. Thank you thank you thank youMy niece bought one after she saw how well it worked for us.
