They Slip and Slide
These are great in theory. However, they do not stay in place at all. The slip down your face when you are talking. They are also very hot. Wearing a mask is hot enough, but these actually made sweat drip from behind them. When they were in the proper place, they really did help hold my mask away from my face a bit for more breathing room. But they don't stay long at all.
