I have been using 10C for about a year, something like 6k miles. First thing you need to know, it's a dashcam, not an action camera. If you want to do cool video editing stuff, buy a GoPro or equivalent. But if you want a reliable camera running in the background, 10c is your rock. What is a dashcam you ask? Well, its main function is recordkeeping, and it records continuously, overwriting old footage. The amount of footage is directly proportional to the amount of storage on your SD card. My 128G card will record about 14 hours before looping. You can save current video with a push of a button, in case you happen to film something really cool. There is also a push button screenshot function, it comes really handy.
And as mentioned above, Sena is a rock solid bluetooth technology. With 10C you can connect to 3 more people (on Sena devices), which in my opinion is the most amount of people you want talking at the same time on the road

We have 3 of these in my rider group, see our collective impressions below
Pros:
- dashcam function. You don't have many motorcycle options in that category, period
- will record and charge at the same time. Sounds like a no-brainer, but $400 gopro does not do that
- solid bluetooth
- amazing microphone, especially if you're in full face
- rugged. Mine hit the ground at 65 mph and broke from the mount, but still works (this may be a contributing factor to the issue below)
- app controlled, change settings and preset radio stations on a fly
- has voice command function, but I never bothered with it
- amazing tech support
Cons:
- Wind noise. You have a box attached to left side of helmet, and you'll be reminded of it at high speeds
- App group function doesn't work, SENA tech support couldn't make it work
- bluetooth has trouble connecting to other riders sometimes, and occasionally will forget a connected device, forcing you to pair again. It's rare, but happened few times
- speaker wire is very think and I had one speaker stop working in under a month. replacement speaker set is still going strong, replaced under warranty and is now secured with tape, which I recommend you do as well
- camera has no manual focus or any adjustment whatsoever (other than lens positioning) Just this past month I noticed that camera doesn't focus as well as it used to. SENA is replacing the entire unit for free, but if it happens again next year, it'll be out of my pocket. Out of focus video is still going to be very much admissible in court, but you're not gonna read license places from it
- PRICE. While $350 is a fat pill to swallow, you can find them for something like $260 on Ebay and store clearance sales. That's what I paid for all 3 of our units.

If you're touring, this is the camera for you. Or anyone, really. If you're a fairweather sunday rider, just record with your phone from handlebar mount and save money.
Hope that helps
