What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Bontrager Flare RT
Two whitelisted cycling outlets tested this exact rear light hands-on and both rate it highly: DC Rainmaker (in-depth review, weighed on his own scale, ran a battery-depletion test) and Cycling Weekly (Editor's Choice, ridden through a wet winter). Praised for its tiny strawberry-sized form factor, weatherproofing and Garmin/ANT+ auto on-off; dinged for confusing modes, Bontrager's reused naming, and a Garmin control-panel quirk. DCR weighed the unit at 23g sans-mount versus the 32g/33g official figure. Neither outlet ran lab lumen or runtime numbers on the rear unit. (2 sourced reviews, 2 lab-tested.)
Praised: Compact, lightweight, tiny form factor (about the size of a strawberry); Smart ANT+/Garmin auto on-off connectivity works well; Weatherproof and reliable through wet, winter riding.
Flagged: Mode settings can be confusing / easy to get lost in the array of modes; Bontrager reuses the 'Flare RT' name across generations, making the model hard to identify; Garmin default control panel can't hold a full light formation solid-on; needs the Connect IQ app or per-light control.
