A little skeptical before buying this type of product that often is not effective dutout well the surprise. 2 small pressure on the pool of spectacle lenses, a light rinse and go ... I end loan. No trace of visible moisture condensation inside the glasses, this has perfectly solved my PB mist is relatively inexpensive, as soon as I'm out of product, I will not hesitate in recommending this product for this supplier for I am very satisfied.
