Is the Manta sleep mask worth the price?

This is where reviewers disagree most sharply. r/sleep contains both enthusiastic long-term users and an explicit regret thread citing light leaks and facial pressure marks, and nytimes.com's coverage was not universally positive either. The adjustable eye cups are the genuine differentiator; whether they justify a 3-5x price premium over a $14 contoured mask depends on your face shape.
