I find this mask painful, it pinches the top of my nose and it's hard to get comfortable while wearing it. I'm not used to mask since I typically use a Theralight bed. I've adjusted the straps and still uncomfortable. The battery lasts about 3-4 days, so not the best if you plan to travel with it. It would be nice if you could charge it through the dock/stand.
I did a lot of research before purchasing this mask. The recommendations for top masks include silicone malleable masks and other harder masks. This one is everything I hoped for. The Velcro could actually extend further on the straps but the lights and the mask are great.
The mask is heavy and takes some getting used to and if you lay down with it to relax it leaves indentations on certain areas that go away. No results yet to review since I've been able to use it 4 times
