Got this brand new in the box did not work. JUNK.
Already trained my dogs to use doorbell but wanted waterproof option for transmitter. This didn't work brand new out of the box. figured it would have a button was skeptical about the touch feature anyways.

Just as advertised. Works good for me.

Only works during warm weather. Not great but not bad either, just not what l'd hoped it would be

This is the doggie door bell you need. I bought others but they didnt last.

got this to teach the dog how to tell us she needs to go out. mounted on a book case by the front door (appartment with no backyard) and put the speaker in a plug near the TV so we can hear it. works like a charm. it doesnt notice when it should stop ringing if its hit with something wet ( like a dogs nose) but it auto stops of after about ten seconds anyways.
