Very bright and many color settings including strobe effect. Lasts about 90 minutes off of one charge. Takes about 2 hours to charge. I'd order again. Get so many people coming up to me to ask where i got it. haha
Pros
The LED lights are energy-efficient, so you can wear the mask all night without worrying about the battery running out
Cons
The mask may not be suitable for those who need to wear a face shield for their job
