Has anyone tried these cloths?
Facebook is constantly advertising them to me, and they have good reviews (but they would, it's their site!), and there are lots of other similar companies too. Do they work?
They apparently use a formula of chemicals that stop fogging when you come in from the cold, or wear a mask, or whatever, but don't harm lenses, including special coatings. Each cloth can be used 700 times, rather than the more disposable offerings.
I suspect their marketing team is just better than the others' but maybe they are better in some way...?
