If you have a iPad you need one of these. I treat mine like a baby and still got some minor scratches within 3 weeks on the glass. I got my screen on perfectly and it majorly reduces the glare and smudges. Best $30 I have spent this month.
I'm in the same boat...I wonder what return policies are for both..and how customer support is..that's probably a bigger deal than the minor quality differences, if any. Let us know what you chose! I never opted for antiglare on my iPhone as the 3GS seemed to do fine..the iPad is tough with even overhead lighting, let alone outside. Also, I am tempted to try a much cheaper eBay option as mot of these companies are not producing their own product just rebranding the same one.I've used these on my iPhone before and I love them. I'm definitely looking into one for my iPad but I'm trying to decide between PS and Steinheil.
What led you to change from sgp? Between the two I was leaning toward sgp. I still think these are way overpriced and am looking at trying some much less costly versions.I just received my Power Support antiglare film in the mail today... but I'm not installing it until my SGP antiglare film needs replacing. $25 is a bit much to just pull the old film off and discard it after only a few days of use.
There really is no perfect solution for this -- a glossy, sharp screen is going to show fingerprints and smudges. Whether you get antiglare film or crystal film, you need film -- the glass is going to get scratched if you don't protect it.
