Attached (I hope) is the invisible shield product I got. It was like 17 bucks (Target) and you only get one so a little terrifying to install, but it's been great! And they claim it has a lifetime guarantee, so they theoretically would send me a new one if I complained.
The installation is interesting...the back side isn't super adhesive, but they give you a solution and mini spray bottle that you put on your fingers and then all over the back of the shield. You then squeege out the bubbles to the edges and mop it up. They said that the microbubbles would go away after a day or so, and that's absolutely true. It peeled up a little by the edge, but I reset it with some of the solution and so far so good (may be the fault of my case pushing on it a little).
This one is anti-glare, anti-smudge and now that I'm used to it, I LOVE it. I will say that the people who warn about a mild degradation in picture quality are partially right. It doesn't really lead to a lower quality viewing experience, just "different". The brightness shines through perfectly, but it's a little fuzzy, almost like a feint mist. However, that's the trade-off that you get for reduced glare and ESPECIALLY reduced fingerprints. Seriously, I essentially never have to wipe my screen. Another underappreciated benefit of it is that your fingers don't stick to the device as easily on the matte finish, which makes games and gestures easier to play.
Hope this is helpful to someone. Thanks for the help.
P.S. - To the person above who said that I could have got a replacement one from Otterbox, they're probably 100% right. However, I had a bad experience with that one and wanted to try the anti-glare, so I just went and picked out my own.
