Pros and cons

- Four sensors and 5–9 / 9–13 dark ranges

- Optical class differs across YesWelder pages; certifications not confirmed
- Reports of early headgear failure and occasional arc flash
Our review
YesWelder lists a 3.93 × 3.23 in (100 × 83 mm) main window plus side windows at a fixed DIN 5. Those side windows never darken further, which is why some buyers describe them as 'not darkening' — that is the design, not a fault.
Four sensors, a DIN 4 light state, 5–9 / 9–13 dark ranges and solar plus CR2450 power are on YesWelder's page. Optical class appears as both 1/1/1/1 and 1/1/1/2 depending on the variant page, and no standard is named.
Buyers like the view; the complaints are headgear durability and a few reports of arc flash, so set sensitivity high and check it before long sessions.
