Sorry can't help on the one you link to, but I have a really cheap one from pyro skins, matte anti-glare and have never been happier with a screen protector. It was not advertised as as anti-rainbow, but I've never noticed any rainbow effect.
I do have issues with the cloth they sent being low quality, but the screen protector and case is great. I was obsessed with finger prints on the unprotected screen I thought I was gonna wear it out just from cleaning, but since putting this one on, I haven't tried much at all cleaning the screen. Basically because it looks and functions so great while on, seems more responsive than without it, I guess I got used to it looking like crap with the screen off.
Don't think I could get it up look clean while the tab is off anyway.
Another point I should mention is no matter the condition my finger is in, moist, dry, or in between it always seems to respond the same... great.
Edit: Just looked at the price and for that much it better apply itself and be replaced instantly for free "before" you scratch it.
Hopefully someone can give you a personal experience, but most people wont spend that kind of money for just a screen protector. I paid a tenth of that shipped.
