Finally - an inexpensive, DIY, wireless doorbell you can count on.
Offers more features and works better than anything you can buy at your local hardware store - and costs less. Great product.That's grandaughter Ruby at age 3 doing her famous Sherlock Holmes impression (cropped photos fit nicely in the little covered space below the button).

all around great
would like more single chime choices, other than musical versions. Otherwise excellent for the price and quality.

Some information would be helpfull
Did not come with any manual or installation/setup guide. No contact information for the manufacturer even though the add says I year technical service and easy contact. All mine came with was the door bell and receivers.

Fine for the Job.
I like this doorbell a lot. The sound is not all that great, but the chimes are unobtrusive and don't hog a whole outlet
