well, im quite anal on this screen protector thing, cause i realy want it to be perfect. and i don't like those matte ones cause it still shows fingerprint and dirts and it make my iphone screen look like a CRT monitor, so grainy. so far i've tried theese and here's my thought:
-SGP ultra crystal - cuttings is perfect, but the screen protector it self is not so crystal clear, you can see some "grain" on them , i suspect is their glue that make it look like that. another thing is that their glue is not so good cause it always lifting up in the corner. i give them score of 6/10
-SGP Oleophobic - very good in the first week also, cutting is perfect, but it loses its oleophobic after a bout a week, and then it become the same as the ultra crystal, but this one is more prone to scratches. score 6.5/10
-SGP ultra fine - this is matte type and i don't like it at all score 4/10 for their perfect cutting.
-Power Support AFP Crystal - perfect cut, very crystal clear, mind you but i buy the japanese version which clearly write "AFP" anti fnger print on the packaaging but it still does shows finger print like any other crystal screen protector out there. but this is the best in teerms of crystal quality. it's sooo damn clearr. and its easier to apply than SGP one, cause SGP one are using sometipe of glue that shows some specks or blemishes if you don't put them perfectly. score 9/10
-Martin Fields - the best cuts out there, excellent claritttty, but it does shows a little bit of the rainbow effect. their protector is the thickest of them all, so it may cause problems with some case. but it does "protect" the screen more because of that. score 9/10
now im using martin fields for my back cover and power support for my front screen, great combo i must say.
I am glad I've found and read this thread. 10-Dee-Q, your review is very useful and I am as anal on screen protector as you.
Tried the antiglare and clear version from Power Support and SGP before on 3GS and I definitely agree with you on the film lifting issue with the SGP clear screen protector.
Recently I tried their SGP crystal clear on 11" Macbook air and same lifting problem occurred, despite the super clarity on the film. Basically if you have to lift up the film to pick up some specks of dust, the 2nd time you lay down the film, the edges of the film won't stick.
Not so much with their antiglare version though. In fact, I find the SGP antiglare is less grainy than the Power Support one on the iPhone 3GS.
As I am getting the iPhone 4S, I think I will go for the Power Support clear version.
I like the blue packaging of the Japanese version of Power Support better.![]()
Do you guys have the link to purchase the Japanese Power Support Crystal?
here's the powersupport japan package that i buy. i bought it in an apple store in Singapore.
glad that i help
anyway just updating.
about the martinfields vs power support crystal clear
the MF is thicker, and there's no cutout for the front facing camera, so that it makes me feel safer about that little camera upfront. but the MF do shows a little "rainbow effect".
the Power support is thinner, the clarity is comparable between both of them. much clearer than SGP one. i don't know why i just don't like SGP screen protector ecxept their anti glare version, but then again i don't like anti glare
another thing is that the Power support seems to be more scratch resistant compared to the Martin Fields.
now im using Power support crystal clear AFP for the front, and Martin Fields for the Back, because of the thicker MF makes me feel a little bit safer
on my iPhone 4
and i'm using Martin Fields for my Blackberry 9900, cause power support didnt make the protector for Blackberries
