I use the boxwave product on my apache. It works great! Hard to tell that there's something there. It's like a thin viewfoil like material that has the stick properties of those things you stick on the windows of your car. If it gets dirty, you just wash it and shake off the water and re-apply. I've had it on my apache for almost 3 years. Would have been longer if I didn't break my screen (no fault of the screen protector, nothing can protect itself from my temper
)and then replace it. Now the protector is on the new screen.
I saw some products on ebay that sound like they have the same properties. Will get them in the mail soon, I'm hoping that it's the same product as the boxwave. I got 5 for under $6.
