Dr. Dennis Gross Mask

The mask works but has battery issues and is priced accordingly. I’m not sure if there’s any fix. Open to offers.

A normal session with the mask is 3 minutes (it shuts off automatically after that, which is what it’s supposed to do). Due to whatever is going on with the battery, this particular mask can be used for about 1.5 red light sessions before it has to be charged again, although it only takes a minute or two to charge enough to be used for another full session. Honestly, not a huge deal if you’re only using it for one red light session at a time.

I’m not sure why, but the blue light setting only goes for about two minutes before shutting off. And please note that the mask can’t be used with red and blue lights on at the same time. The mask technically supports that, but this one shuts off immediately when you cycle to that setting.

So basically, it’s functional for using it for one red light-only session at a time before charging again briefly.
