Angelcare Under-The-Mattress Rechargeable Baby Monitor

The Angelcare AC420 is a sound monitor with some easier to use features that parents will be looking for like sound activation and an adjustable mic sensitivity. It has a long battery life of 30 hours for the parent unit, the batteries are AAA instead of rechargeable so you'll be buying batteries regularly if you use this product without the plug-in base.

However, this unit has poor sound quality with intermittent sound dropping and poor range connection that had trouble staying connected. It also lacks two-way communication with the baby, something many parents will think is a dealbreaker.
