I've ordered some myself and intend to try them, but keep in mind that (as far as I can remember) the storms and basically all the Verizon phones up to this point have been resistive screens, meaning they work by pressure on the screen, the Droid is capacitive meaning it needs contact with a grounded source to work...like your finger etc. (thats how it has been explained to me at least).
Not saying the Zagg shields wont work, just don't base your expectations off of past experience.
Ordered mine a week ago. It shipped out on Friday...same day I got my phone. I had one on my voyager, itouch, and my GF's touchscreen phone. No problems with the sensitivity at all. Best screen protector there is.
