just purchased the Steinheil Crystal. i would have also bought the Steinheil Anti-Fingerprint but they were out of stock.
I just installed my Steinheil Crystal like 5 minutes ago, and so far I am extremely impressed. I went through an entire pack of the crappy Verizon ones without getting one to look remotely acceptable. I got the Steinheil on first try and it looks and feels fantastic. It is literally invisible, I can't even tell that its on.
One trick I used that I picked up from these boards was to apply the protector in the bathroom after letting the hot shower run for a few minutes. The idea is to increase the humidity a great deal to knock all of the floating dust out of the air so it doesn't get caught under the protector and ruin the application. Seemed to work well, as I had none of the problems with dust I encountered trying to apply the Verizon ones in a normal room.
My wife has Zagg InvisibleSHIELD and i have to say ITS HORRIBLE, i absoultly hate the feel of it, the touch is sticky, you can't slide your finger with ease on it.
I would go with none.
Heres the video I saw before,
after seeing this I was more comfortable to not put a screen protector on.
However I will admit I really wanted one on when I first got it, I failed 6 times with the verizon ones they sell, could not get it on with out bubble(s).
after having the phone since November, its really not needed.
Try the hori screen protector, i originally put on a zagg but coudn't stand the look on it. Its originally made for the psp but fits my droid perfectly(stops right below the headphone part.
Keep in mind though I had two available and one fit while the other didn't, but others just don't compare in turns of quality, i'll get a pic of my droid with it on when i can
I use the Seidio screen protectors from Seidio.com and they're great. I bought 2 just in case, but the first one went on perfect and you can't even tell it's on.
As to the people saying you don't need a screen protector, you're completely wrong, there are numerous people saying that their screens are already scratched. Sand is the leading cause of scratches on glass.
Gorilla glass is not scratch proof, it's scratch resistant and the key test is thrown out because they're made of brass and they won't scratch glass. The silver keys you see are only silver in color because they're plated with nickle and that won't scratch glass either.
I have had my Moto Droid since the middle of November, I bought the vzw 3 pack and couldn't get them on right so I just left it alone. So far no scratches on the glass, and I have dropped it on the sidewalk, floor and the only thing is the black metal around the glass is scratched.
