I already purchased the TPU glossy case so all that was exposed was the screen.
I searched around for some screen protectors and saw these. When I saw the price for these FIVE protectors, I expected them to be absolute crap. I mean *40 cents* per screen protector? But since the rest of the phone was already very well-protected, I said sure why not. I thought to myself, "It's just a piece of plastic anyway. You can't really mess that up, right?"
It turns out that these are actually not bad. They are cut decently well so that it covers the full screen, all the way from the top to the bottom, ie covering the capacitive buttons as well. Maximum protection: I love that. There is a little bit of area missing however: a few millimeters on the top and bottom. But 90% of the screen is covered, and I'm happy with that. As long as the vast majority of the screen is protected, that's what matters. The phone isn't going to be gouged in those few missed 2 or 3 millimeters.
For the application, I used the Best Skins Ever instructions ( [...] ) because I have been using their skins for quite some time and I am familiar with their procedure from having done it more than half a dozen times on multiple devices. (I didn't purchase BSE's Sensation skin because it wasn't available when I purchased these EZGuard ones last week.) (Note: These EZGuard skins do come with a page of instructions with a "dry" and "wet" method, but the BSE method is more complete. And like I said, I am already familiar with their procedure.) The dish soap **REALLY** helps by the way. It allows you to move the skin around extremely easily while it's on the phone, so you can get it in the perfect position. Use a squeegee and paper towel to squeeze the water out and instantly dry it up. Once the air bubbles are all gone, use a blow dryer afterwards if available.
Anyway, after using the phone through the screen protector for a couple days, I have to say that I am impressed. I have had no with touch sensitivity using my phone, and it still looks great (no orange-skin look).
The only bad part (and why I am giving it a 4) is that it feels somewhat rough to the touch, almost sandpaper-like. It's definitely not terrible, but it's certainly not glossy smooth.
Overall, I would definitely recommend these for the price. If you're already buying something on Amazon, throw these in your cart. It's a few extra dollars for FIVE skins. Impossible to beat that, especially considering Zagg etc are $20-$30 for ONE skin (absolutely ridiculous). The price can absolutely not be beat, and I would certainly purchase these for my future phone(s) if I can find them at this price.
I'll update this review if the screen protector starts peeling off or getting massive scratches or something, but so far so good. And if it does happen, well, I still have 4 more skins to use up, right?

[Edit August 8, 2011]: Sadly, I have to say the "roughness" got to me and I am no longer a fan of these protectors. It really does get very rough and makes my phone unpleasant to use.
I ordered the Skinomi screen protector and WOW, what a difference. It's smooth as butter. *AND* it actually covers the *ENTIRE* screen, from top to bottom. 100% coverage. I didn't realize just how much the EZ Guard screen was missing on the top/bottom (ie just how poorly it was cut) until I put on the Skinomi.
Not only that, but the Skinomi has a life-time guarantee. That's amazing. I would definitely no longer recommend the EZ Guard skins unless price is an issue and/or you have multiple phones.
For the price, you definitely can't beat the EZ Guard. But you get what you pay for (a very rough skin).
