Negative Positive
Title: wont recommend it.
Review: I was happy using this product for the first couple of months. Then I noticed a small crack on my lens. I never thought that it would be from the cleaner until I started cleaning my other pair of glasses. I saw crack initiating almost from the same spot. It might be just my glass but am sure these kind of vibrations are capable of initiating (and later propogating)cracks at points of high stress concentrations. (You can ignore this last line, that was just my ME background talking :-))Now I am back to my cleaning swipes.
Is the review positive or negative?
