“if you want something with more power but a little bigger Thrunite Archer 2A V3 (I got one for myself like a week ago and I love it already). For comparison it's as long as a modern smartphones length.”— whitecow on Reddit
“ThruNite Archer 2A V3 (this was chosen by the wirecutter and works well enough; it helps having 2 lights so we can each have one)”— tsuehpsyde on Reddit
“Back in November I got the "ThruNite Archer 2A V3" and today my new Powertac Valor arrived. In a quick comparison I think I like the Powertac more, it's quite a bit brighter and the center beam is more focused.”— flatmind on Reddit
“I'll be the first to say they reset my standard when it comes to firefly mode.”— ch1ir on Reddit
“Personally I would choose the Wurkkos FC13 with SFT40 over the SC31 Pro. It's a really solid light for the price.”— bunglesnacks on Reddit
“Looks a bit disappointing, the M2 CULPM1 looks better IMO.”— @CorradoVR6z on YouTube
