Review on The Basement Watchdog BWSP 2,600 GPH at 0 ft. and 1,850 GPH at 10 ft. Battery Backup Sump Pump System with WiFi-Enabled 24/7 Monitoring Controller by Patrick Locke

Product was brand new when received as stated. Received a box that looked very old. Since then I've had problems with the siren. Had contact with the manufacturer. Find out, my new serial number watchdog timer is 5 years old. I used a new marine deep cycle battery that is eligible for warranty purposes, but a 5 year old product is not compatible with this battery. Hoping for redemption. Hard to believe that the seller sells such old devices. We will dispute this with Amazon for a refund
