Review on 🔌 Mini Bluetooth Receiver: Wireless 4.1 Aux Adapter for Audio Stereo Systems - Hands-Free Car Kits with LED Indicator (Black) by David Sanchez

This device is totally unusable! According to the instructions, charge for 30 minutes and play for 4 hours. I charged it for an hour, plugged it in and it was at 10% battery according to the notification on my phone. I put it back on the charger and let it charge overnight, 12 hours and tried again and it was only at 20% and dropped out immediately just trying to connect. As soon as the device connected to my stereo to connect my phone to play music via Bluetooth, the connection dropped and I had trouble reconnecting. The lack of connectivity (when standing nearby) coupled with the lack of battery power renders this device utterly useless!
