Overpriced for what it is
"The mask is a good idea in theory and I got it at a discount which made the cost comparable to the cost of some premium fabric masks so it seemed like a reasonable deal. However, in practice it falls short. The vibration feature is too weak to be useful and does not really improve the experience. If anything, a product like this needs to provide a noticeable massage effect to justify the built-in mechanism. The noise is also more disruptive than expected, especially because the mechanism sits directly against the head. When wearing earplugs, the sound is very difficult to handle and disrupts sleep. The other issue is comfort. Because the mechanism is hard, the mask is not as easy to sleep in as a normal fabric mask, and it limits the positions in which it feels comfortable. Overall, I do not think it is a bad concept, but the current execution does not really work for me as a sleep or massage mask."
