Amazon.com Review:
Dogs as well as cats can be taught to press this paw-shaped transmitter to signal when they want to go out or come inside. Using FCC radio frequencies, the remote control paw activates the wireless doorbell up to a distance of 100 feet, and can be set to a chime choice of ding-dong or dog bark. An extra paw can be placed near every door in the house, indoors or outdoors (protected from the elements), either set on the floor or wall-mounted. The sturdy plastic paw measures 5 by 4 by 1-/3/4 inches, and requires one 9-volt battery (not included). The chime requires three AA batteries (not included). Lentek covers the pet doorbell with a two-year warranty against defects. --Ann Bieri

Rating : - Rings randomly, basically usesless.
For the first several weeks, after my dog figured out how to use this product it was great. Unfortunately, after about 2 months it started acting up, where the receiver would chime at random times. As you can imagine this was quite annoying, and essentially made the device useless.

I don't recommend it.
