My friends with Cardo complain about interference, noise, and blowing, and many times I hear them with a robotic voice, and to fix it, I have to close the intercom and reconnect with them. Also, there is no easy way to connect with another intercom like with other brands, which can be done through an app with a single button. And finally, once I connect with someone, even after a while, while I’m listening to music, out of the blue it starts searching for intercom and annoys me that the connection failed even though I haven't set it to search.

On the positive side, the good sound quality when I listen to music and nothing else!

I have been using it for about a week and it is excellent. Good sound quality and clear, excellent radio, very easy to use on the smartphone. I highly recommend it.
