One of My Sena 10 units out of 2 went bad. The unit was out of warranty. Sena does not have a repair center so I could not send unit in for repair. I then asked just to buy a new module. I was told I would have to buy a complete new set. This not a customer friendly policy. It seems that once the unit is out of warranty Sean does NOT care about its user base. I am extremely disappointed and will not use Sena products anymore as a result of Sena not having a repair center or at the least a means of buying the necessary replacement parts at reasonable cost.
