Well known as one of the best brands when it comes to cases. Thus I believe it is fair to give them a segment of their own in this best list. To justify their premium pricing, they offer equally premium features like antimicrobial materials that keep that protect the case against bacteria. It couldn't be any different for their Flip 3 case. Symmetry Series Flex case offers a transparent back that is accented by more rigid plastic for the frame, giving adequate protection for your device while also offering antimicrobial protection and the security of a premium case brand.
