Dakota Alert WPT-3000

We're very pleased with it. No false alarms, no misses either. We no longer need a doorbell.

Installed 31 July 2006. Batteries appear to last about 9 months.

Replaced east side battery on 26 January 2007 because of battery defect. Replaced both batteries on 7 May 2007. Alarm was still working but sounds twice for a single car when the battery is weak. Replaced east side battery on 2 Feb 2008, was sounding twice.

In November of 2009, one of our units started randomly sounding at odd times. I contacted the company and was instructed to send it back. They returned a new one, at no charge! This is after nearly 5 years of service. What a great company!
