Today after almost a month i have received the uniq optix clear glass. Coverage is crap, oleophobic coating seems good and edges are very rounded and nice to the touch. For now from what i have personally tested, i can tell that the coverage of protectors is (from worst to best when it come to horizontal coverage):
Belkin, optix, esr, spigen, ultraglass
