Review on Enhanced Range Wireless Lights: Remote Control 500Ft to 1000Ft by Doug Virden

The product itself works very well. The remote turns my pond's waterfall on and off through the stone and plaster walls of my home __ about 350 feet! Sometimes the antenna needs to be extended. But that might be because the battery typically drains in just three days: it costs about $5 every 3 days. a lot of changes. However, I solved this problem by removing the battery from the remote between uses. It seems to me to last 3-4 weeks instead of 3-4 days without a battery.
