We're still using the old smh-10s. They have been dependable and not anything that frustrates us on our small group of 4 tours. I would move up if we grew our group, but so far we like the small group... easy to coordinate vacations, ride distance, keep together and find lodging/food for. We'll keep them until they die... but also found a way to install new batteries if the batteries begin to lose their charge longevity. When the time comes, though, will move up to another Sena product because of the great experience with them thus far. My first was an early Uclear that was horrible. It chased me to Sena. I hope the Uclear line has improved since back then (5 years past). Thanks for the reviews, I like to hear about what is current, the advantages and what works!
