Bought this about four years ago, paired it, put it in my center console and forgot it was there until a few weeks ago when the power cord stopped working.
For a second, I thought it was my cars Bluetooth that stopped working, and then I realized my car doesn't have Bluetooth.
Spend a couple of extra bucks and you'll appreciate the convenience.
I own both the mpow one and this one: https://www.amazon.com/HomeSpot-NFC-enabled-Wireless-Bluetooth-Auto-Reconnect/dp/B00G57CWZ8 This one is drastically better for me, but it's unfortunate that you lose the play/pause functionality.
