I haven't ever heard of opti. I have used xoskins.com for about 2 years and they have tuns of reviews stating they are the best. I have also tried zagg, best skins ever, ghost armor, phantom skins, and a slew of acrylic ones. XO skins has a lifetime warranty and they stand by it. At their stores they have a display with about 10 other companies skins. IMO none of them stand up to xoskins. All of them have either orange peel, they come off easily, or they turn colors. XO skins are uv coated and use a stronger glue than anyone else. I asked them about doing a camera cover last year and they said by adding another layer on top of the camera it will distort it. The camera is designed to focus light to one point, like an eyeglass lens. If you change that, it will distort your image. Thats also why some camera lenses cost thousands of dollars, that glass is made perfect.
