I placed an order for the SGP Ultra Crystal (glossy) and they sent me the wrong one, the matte version!
I decided to put it on anyways, didn't feel like dealing with all of their BS.
I thought it was pretty easy to put on, no problems at all, used scotch tape to pick up the dust specks.
The finish on the matte really sucks! Everything looks slightly cloudy and blurry on the iPad screen. It's also a fingerprint magnet, can see every little smudge. I hate it, lol.
I just emailed SGP and told them they screwed up my order and asked them to send me the UC version, worth a try at least.

But I guess this will do until Power Support gets their films out - have used them on every iPhone I've had and they are always the best!
Update: Wow, SGP actually responded to my email within a few hours... they asked me to verify that I received the wrong item by sending them some photos. Luckily I still had the packaging... will be interesting to see how this goes.
