Review on Instapark Bright Yellow Flashing Battery by Rico Posley

This was one of the most valuable small purchases I've ever made! The alarm has twice saved us from potentially flooding our basement for the third time in 5 years. The alarm clock is loud and we can hear it from every room. So if there is a problem, we will know immediately. The most impressive thing is that I accidentally put them in the washer AND dryer (long story) before installing them and they still work great! I would highly recommend this product to save me hours of store cleaning and flood stress!
