Title: Just one problem
Review: It works. We have just had several days of freezing weather, and the birdbath has been fine ... except. In order to power the de-icer we must plug it into an outdoor outlet using an outdoor-rated extension cord. Rain or melting snow got into the connection between the de-icer and the extension cord, causing the outlet's circuit breaker to flip. Then, of course, the de-icer didn't work and the birdbath iced over. To cure the problem, we packed the connection with waterproof goo designed for use with electronics and sealed everything over with waterproof insulating tape. No more problems with the circuit breaker. If you must use an extension cord to power your de-icer, be prepared to seal the connection. Your local hardware store or electrical supply store may be able to sell you the necessary materials.
