They leave lint: EDITED
Pretty disappointed in these, not only are they super thin and not 'scrubby' enough, but they leave lint on my glasses. They basically smear whatever I'm trying to clean off my glasses around and I end up worse off than when I started. They work fine for a phone (if you want to use 2 or 3) but are worthless on glasses. EDIT: The company contacted me and not only refunded me for my purchase, but also is sending me a different type of lens cleaning kit that will hopefully work better. They have been very responsive and a joy to work with.
