Super lightweight, sensitive sensor, multiple shades (darkening) in the filter, quick activation time, large field of vision. Vibrant colors, you won't even realize you're wearing it. Watch battery indicator on the dial, automatic on/off for battery saving (motion sensor). Rolls Royce of masks. Switch between grinding and welding profiles with the side button outside the mask. (obviously also on the dial)
Make sure you have strong backlighting otherwise the sensor will darken excessively. You'll understand what I mean with use.
