I usually ignore posts like mine but.... I have the Nillkin Tempered Glass screen protector with rounded edges and its sublime. It comes securely packaged in a nice box which contains a plethora of wipes and anti static films which ensure a flawless installation, it was easy for me with the hinge method and I didn`t get any of the cobweb effects or poor adhesive issues as some people have reported. The glass is very smooth with an oleophobic coating. It is much smoother than the stock glass and whilst it still gets fingerprints it`s really easy to wipe them off usually with a single swipe. Overall I can`t say enough good things about it since it was just over $10 aud shipped. I will stress that I haven`t tried any other brands, but I can`t imagine them being better to the extent that they warrant the 3x price difference, support and free replacements may be the only benefit and again that`s not a given. 10/10 for me, excellent packaging, smooth installation, great product and no defects/chipping corners, etc.
I now run a cheap plane Jane one and it looks and feels perfect.
