Title: Wears Out Quickly
Review: All of the plastic Fresnel lens magnifiers have the problem of being very easy to scratch. Even stored in a soft plastic sleeve they will become unusable in a couple of months if you carry them in your pocket or in a wallet. They work fine when they're new. If you don't mind replacing them often they're useful.
