Adhesive is very messy
Had  good ratings so figured I'd try out. Have been using the type with small air pocket. These work ok but are a pain to remove as the adhesive used is very sticky and messy. Very difficult to remove from glasses once you get it on the eyeglass (alcohol works ok; commercial eyeglass cleaner does not work). They stick ok and are comfortable enough but takes 3x longer to replace due to the inferior adhesive used (gummy and hard to clean off).
