Handy for reading at night to avoid blue light. Strong enough to read by on its own. Quick & easy to clip on a book, good product.
Glad I bought one. Makes cleanup much easier as most of the sweat is caught by it. Plan on buying a second so I can always have one on hand.
Slide easily over my glasses and fit beautifully. It didn’t take any time to adjust to the colour change. I use them to watch TV in the evening and now I sleep better.
