Review on EverNary Dog Door Bell Wireless Doggie Doorbells For Potty Training With Warterproof Touch Button Dog Bells Included Receiver And Transmitters (1 Receiver + 1 Transmitters (W)) by Jay Huang

Update: I lowered the review a star for the seller emailing me the same instructions I already had that still don’t do what I wanted. Leave me alone. Why do amazon seller think they can keep emailing you over and over. You got my money, I got the item. My review is not an invitation to contact me again.Works well and the puppy took to it quickly. The only thing is I wish the buttons could be set to sound different noises at the same time(front door sound, backdoor sound, food.). We wanted to train our dog on multiple buttons for multiple situations but this system will just ring the same sound for each button.
