I didn't know that a bike could feel "smart", nor did I know how much fun it would be, yet here we are. First and foremost the lights are surprisingly bright, and all of the features advertised worked even better than I expected.
Build: The light and remote clamp cling to the bike quite well, nothing rattles and everything feels very sturdy. The remote clamps into its slot good and tight, but it is not a hassle to remove. The light is not meant to be moved easily after installation, so it is best to choose its placement carefully.
Lights: As priorly stated, the lights are very bright, it helps road visibility immensely. The turn signals are easy to trigger, and they have an audio queue so you can tell if they are active or not. The different settings on the brake light are each useful in their own way.
Alarm: This alarm is a lot of fun, you can adjust the sensitivity, but I found the default to be reasonable. The alarm is very easy to arm and disarm via the remote, and is loud enough to make you jump even when you expect it.
Battery: I haven't done any tests to figure out the battery life, but it is enough to go on a lengthy night ride without issue. I left the light in alarm mode for several days, and it remained active the whole time. When I eventually checked the battery, it was at the same level. So at the very least the alarm standby lasts a long time.
