The Tommyknocker is a USB, all digital doorbell that does not need any audio cable or microphone to load sounds. MP3 sound files may be uploaded to the Tommyknocker USB memory stick via a computer with the help of our website and may be any length up to the size of the stick. The website http://www.tommyknockerdoorbell.com offers users instructions on setting up sticks, wiring diagrams and installation instructions as well as a sound editing tool. The sound editing tool is designed to enable users to select desired sections of music or favorite sounds, perhaps focusing on the introduction or main theme for a custom effect. Pricing runs around $170, but is well worth it if you are sick and tired of your current doorbell.
Personally I like this idea and figured it would only be a matter of time before a gadget like this came out. I don’t have a review copy, but if and when I do, I will review it and post it here.
