    I like the product but I’m unhappy with the battery life. I work 8 hours a day but it’s only been lasting 4 1/2-5 hours max.

    I’ve had a lot of my work colleagues interested in the product but I had to be honest with them regarding battery life.

    Did not work for me

    Posted by Unknown on 4th Jan 2017

    I ordered the Bluetooth microphone and transmitter for my Kenwood radio. I work in hospital security and this setup would not work in this environment. When I received a radio transmission, I could not understand what my officers were saying. Also when I would try to respond my transmission was broken up. I called Pryme technical support and they told me that there was probably a piece of hospital equipment interfering with the Bluetooth transmitter.
