Very impressed with the Sena S60S. Having had on bike comms for several years ( a cheap but functional system) my biggest frustration was being unable to have Sat Nav and Comms working simultaneously. I always had to manually select one or the other, then sometimes the Sat Nav would cut out the comms just when I needed it to work. This is all solved with the Sena S60. I can have Sat Nav guidance audio, comms and music all working and it all works together seamlessly. Also the Mesh works really well, especially in Mesh 3.0 mode where so far I have been unable to exhaust the range....I know it has a range just haven't found it yet! I have used it with some friends in Mesh 2.0 mode and there is a noticeable range drop off on that, probably around 4-500metres but was able to make it work acceptably. Plenty of options for mounting and a fair selection of additional mic's and fittings come with the units. On the negative side someone needs to explain to me why it's cheaper to buy two individual units over a pair in a kit, and also I have had one unexplained switch-off which caught me out... Not sure if I have somehow inadvertently managed to power it off or if it is some software glitch. (there was no audible warning it was powering down- it just suddenly became apparent it was off) Will for now put it down to user error as it has happened only once.
