What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
BenQ ScreenBar Halo
Two whitelisted outlets cover the original BenQ ScreenBar Halo, both hands-on but qualitative with no lab measurements. TechRadar's long-term owner calls it an eye-strain-killing accessory it can't live without, while Tom's Hardware judges it excellent yet overpriced, largely matched by a $60 Xiaomi except for biased lighting. (2 sourced reviews.)
Praised: Noticeably reduces eye strain and screen-time headaches in daily use; Premium build quality with an extensive, feature-packed control set; Rear biased lighting is the feature that sets it apart from budget bars.
Flagged: At $179 it is expensive and mostly matched by a $60 Xiaomi except for biased lighting; The original model is now discontinued and hard to buy, superseded by the Halo 2; Requires keeping a separate wireless puck/controller on the desk.
