Review on REVIVEL 3D Bracket Silicone Bracket Face Comfortable Breathing by Jonathan Bennett

First off, the thing doesn't work well with masks and I've tried different types of masks from paper to cloth. Third, after putting it in the car glove box and then pulling it out, I found that the heat in the car caused the silicone pad to flatten rather than bounce, so it's completely useless. I'll keep looking for something better until we stop wearing these damn things!
