    Constantly Disconnects

    Posted by Glenn Johnson on 28th Jul 2018

    Not happy with the constant disconnections, suspected it might have something to do with it not being battery powered and relying on the radio's power

    very happy with this purchase

    Posted by Chrissy on 13th Dec 2017

    If you’ve ever experienced wires & cords to be hands free ( basically looking like FBI with the plug in your ear ), you will be overjoyed at the freedom the pryme blu dongle gives you!! My husband has to wear hearing aids and the Bluetooth dongle works beautifully with his hearing. We plugged the dongle in to our radios and charged them overnight. We are using a Motorola Bluetooth earbud to pair with and the quality is great. We use this set up for our Church Security team and it’s easily disguised/covered up. People just think your using it with your phone...if they see it. And no more wires all over! Getting dressed means clicking your radio on and putting the earbud in your ear! Simple and fast!! We couldn’t be happier.....
