As a simple Bluetooth headset device that can interact with your phone allowing you to listen to turn by turn Google Maps/Waze instructions or some of your favourite music ... it is ok I suppose. Others commented on the complexities of installing it in the helmet without any instructions. But what really disappointed me was the Voice Commands! Shocking! So bad in fact, I consider it dangerous. It rarely understands any of the commands and naturally I get rather enraged. When Mesh is turned on, music and Waze instructions are turned down to almost inaudible, except for the first utterance. I have also got the Sena SMH10 and the SRL Neotec2, so I have experience with Sena headsets. So, to find myself so frustrated with this latest SRL-03 is a huge disappointment. "Codfanglers!"
