Review on Ultimate Shield: Kenneth Cole Neoprene Continuous Protection for All-Day Defense by Orlando Mohr

The fan is a good idea and it works, but it's so heavy that after a few seconds the mask won't stay on your nose. Protocol. There's also no wire or anything on the nose to hold it in place, preventing a proper fit. Also, you should charge the fan EVERY time you plan to use it (because it doesn't hold a charge well). Too many problems for this overpriced mask.
