Review on Babytone S2 Baby Sleep Monitor with Heart Rate and Movement Tracking, Free APP, Bluetooth & Base Station with Display Screen, Wearable Foot Monitor for Baby Care, Suitable for Babies aged 0 to 3 Years Old by Melanie Lang

I bought this as a reliable travel heart rate monitor for my 2 year old at night. The device works great. The ability to set custom alarms is great, and the device itself is easy to carry and charge. Charging on the monitor lasts about 2 nights and on the base station for 3 nights. I will say that the base must be left in the room with the child. The alarm is loud enough to go to other rooms. The Bluetooth signal is the only downside. It is not enough to keep in touch with the base all over the house or to make phone calls. Otherwise I love this item.
