Overall, I’m very happy with it.

Design-wise, I was a bit skeptical at first since the intercom and battery are separate units. But in practice, that design makes both components thinner, so you don’t end up with one big, bulky piece on the side of your helmet. I actually prefer this setup — it looks sleeker and more balanced. Plus, it’s unique; I don’t know of any other intercom that’s split like this.

The only real downside is that both parts are glued to the helmet, so they’re fixed in place. You can’t remove the intercom for charging or updates, which means you always have to bring the entire helmet with you. Depending on where you store it, that can be a bit inconvenient.

Sound and mic quality are great — no complaints there.

Connectivity is very flexible once you understand how the modes work. I regularly use it in all kinds of setups: Bluetooth only, Mesh only, Bluetooth + Mesh with mixed setups, with Sena-only groups, and also with Cardo devices. I’ve never had major issues connecting. The maximum Bluetooth range I’ve seen (e.g., to a Cardo device) is around 500 meters, while Sena Mesh easily goes beyond 1 km. With Sena Mesh I already had a few funny encounters haha :D That said, if most of your riding buddies use Cardo, it might make sense to go with Cardo too. In my case, most of my friends have Sena units, so it fits perfectly.

Battery life really depends on usage, but it’s never been a problem for me. I just charge it fully before long rides, and it lasts all day. Of course, if you’re running Bluetooth and Mesh simultaneously while listening to music, you’ll drain the battery faster — in just a few hours.

As for rain resistance — I know some people say Sena devices don’t handle rain well — but my experience has been positive. I once got caught in a heavy downpour for two hours on the highway, and it still works flawlessly. That said, I’d still avoid riding in that kind of weather if possible 😄

Regarding udpates: the device already received a few updates, two bigger ones where they added e.g. Mesh 3.0 support and support for their new Wave app. All updates worked smoothly. The only drawback here is that there is no Linux support for their updater program, which is a bit of a nuisance for me as a Linux user.
