I use the Sena 20s and it works very well. I have a love hate relationship with it. The issue I have with it, is it does to much!! I like things that are simple to use. This thing is like having a smartphone attached to your helmet. I have a tendency to push the wrong buttons for the wrong things at the wrong time and everything gets out of kilter. When I do my part correctly it's an amazing piece of equipment, but when I accidentally push or hold the wrong button I have thought about throwing it off the next bridge I cross.
