Review on EverNary Dog Door Bell Wireless Doggie Doorbells For Potty Training With Warterproof Touch Button Dog Bells Included Receiver And Transmitters (1 Receiver + 4 Transmitters) by Richard Koh

The setup was relatively simple. The instruction provided was too small for my poor eyes sight. I obtained the programming instruction in the "answered questions" section. I had a challenging time training my usually intelligent puppy (10 lbs). He often learned a new trick in a couple of training sessions and consistently reinforced it after that. But for the life of me, I could not get him to bump the transmitter because he is forbidden to scratch or paw anything in the house. I decided to place an extremely minute amount of peanut butter on the transmitter, and presto, success! Immediately after, ever so often, he pressed the transmitter with his nose/tongue. I patiently allowed him to go out every time and conveyed the importance of pressing the transmitter to go potty. The tedious process of training went on for a total of five events, letting him out and patiently waiting for him with a copious amount of encouragement for him to do his thing. He finally understood that the transmitter was to notify me to let him out to potty. Side note, he is an indoor puppy and dislikes being exposed to direct sunlight. I am very pleased with the purchase. Durability is unknown. The difficulty of replacing the battery on the transmitter is unknown. Time will tell when the time comes.
