Review title: battery change purgetory
Product review: Buy this unit if you like being woken up several times a year with shrieking false alarms for low batteries. I've read the product description and the way these work does not jive, when the battery runs low (not too low) be prepared for a bad experience, even after you replace the battery be ready for a few minutes of alarm shrieks that 'confirm' you've installed the battery right. Don't worry that your previously sleeping kids are now screaming and crying. Seriously, the battery is a back up for this system. I take great pleasure in tossing these things in the trash.
