Review on Enhanced Viper 5806V 2-Way Security System with Remote Control by George Saunier

A few years later and it still works. The only thing I don't like is the need to replace the batteries in the 2-way LED like clockwork every 8-9 months. Even then, the range with new batteries is as stated, ie line of sight. As the battery life decreases, so does the range. I've read about an LCD remote with terrible battery life so I can't even imagine how much worse it is compared to 8-9 months of battery life.
