I was a varia skeptic…now convert. If this industry wants to talk about “game changing” items, this is one that actually could stand up to the commentary. Being able to ride along in a paceline, even mid-pack, and get the notification that a car is approaching from the back really does improve situational awareness. In the month that i have had it, its saved me a few close calls from drivers sneaking up and not giving enough space.
If you do go the route of a normal light, the only one i would recommend is the bontrager Flare R. That thing burns retinas and makes you visible on even the sunniest days from hundreds of yards away.
