Review on 🐾 Lentek Pet Chime Cordless Doorbell Training System 2 Piece Set - Pet Chime Receiver and Pet Paw Transmitter, Battery-Operated Doorbell Trainer for Cats, Dogs, Kittens, Puppies - Ideal for Housebreaking by Amy Smith

I really like the product and will continue to use it. My dog learned this in just a few days. The biggest downside, however, is that the wireless receiver doesn't work within 100 feet as stated in the product description. Luckily I can still hear the listener upstairs, and I installed it a few feet from the paw. The biggest problem is that my dog squeezes his paw to put pressure on it and it easily gets out of reach so he doesn't make a sound even if he hits it right. I'll try to nail it to the ground to fix it. So, the product works, just not as described. And you need to make some adjustments to make it work for you. DO NOT purchase this product unless you REALLY want to get the receiver close to the paw.
