I've tried a few sleep masks and this SleepMask is by far the most comfortable. The 100% blackout really blocks everything out, and the three quiet vibration patterns are surprisingly soothing rather than distracting. I use the gentlest setting and it helps me settle down faster and I wake up less during the night. It's not magic, but as part of a wind-down routine it genuinely helps. The fabric feels soft on the face and the vibrations are quiet enough not to bother my partner.
