Review on SUNITEC Hands-Free Bluetooth Cell Phone Car Kit - Wireless Speaker AUTO Power On 🚗 - Support Siri & Google Assistant - Bluetooth Receiver Handsfree Speakerphone with Visor Clip - BC906 by Michael Syph

Works great, auto on/off works great. If Bluetooth is off on the phone and the speaker is on, it will beep until you turn on Bluetooth to connect. Since I'm using this in the car, it feels like a great reminder to turn on bluetooth on my phone. Always leave the speaker turned on. The sound of the voices is clear and others say the same. Nice device, works as advertised.
