I've used PS anti glares on all 3 generations of my iPhone, so I had planned on getting one for the iPad, but the price was too much to swallow, especially given that nearly every time I've applied one, I've screwed it up the first time and had to buy another. I've since learned to buy 2 right off the bat. For the iPad this meant a $60 investment.
This time, based price alone, I went with the Speck anti glare, which comes in a 2 pack, for $25. They fit exactly the same as the PS. Some companies make the home button hole too big or too small...the Speck is just like the PS, i.e. a perfect fit. Oddly, this time I managed to put it on correctly on the first try. I'm happy to say that the Speck seems every bit as clear as the PS, perhaps even a bit more so. It doesn't have the granular sparkly effect the PS has. I think this is because the surface isn't quite as rough. It shows oily marks quicker than the PS, but I'll take it over the PS at half the price.
