There are no other tempered glass screen protectors for the S III. This is the only one out on the market. The other cheaper screen protectors that you are referring to are PET films, which are in a completely different league than this.
SGP might be making the Glas for it .. but will still be priced high, and I would present them the same argument.
Its in a different league because its glass?
Who cares if its glass?
Its only in a different league because of the PRICE and your marketing, making people think they need that.
You (and many others, but I refer to you because you are actually here on the forums) are the MONSTER (brand) of screen protectors lol
I have seen SGP Glas protector chipped and shattered...
Tell me why, in everyday terms and practicality, that someone should spend $30 on that when I can spend $14 on the Ultra Crystal, which has 4H hardness (which is more than enough by the way).
I saw your photos on the site, and I dont see how that is ANY better than the Ultra Crystal.
Our shatter-proof design keeps both you and your screen safe from cuts and scratches. When suffered major damage, the screen protector will crack and not shatter much like a car's windshield.
That quote along with the image of it describes exactly what happened to my SGP Ultra Crystal for my Motorola Milestone a long time ago when it took a hard impact from a point in the center of it. Guess what? I paid $12 for that...
This is for the people that buy what they dont need just because it has nice looking features and numbers that they will never use realistically.
ie. Lamborghinis - very nice, very pricey, but why buy one for everyday use. No practical point. (although yes I would love one)
If these things cost 15-20, thats more reasonable. But $10 more just because it is glass even though it wont REALLY make a difference...
I could issue a challenge and GUARANTEE that if someone were to use your screen protector for .. 6 months, and a different one for 6 more months, there would be NO BENEFIT to using yours. By that I mean, their actual PHONE SCREEN, would not have any damage with EITHER screen protector applied.
I would put money on it.
