Review on Bluetooth Transmitter Outdoor Learning Education by Eddie Baglien

Strike 1. Although there was a lithium battery warning on the box, no battery was included. Strike 2. The app mentioned for using this heartbeat checker device is not even listed on the iPhone App Store. Other heart rate apps that are oddly listed in their printed instructions will not work with this device, or may only work if you pay a subscription to use their app. Very strange. We are returning this inexpensive but still unusable item. Strike 3. THEY GO OUT!
