Sticking to my previous disclaimer, nobody at Zagg or anywhere else is paying me or giving me anything for this.
I'm a big fan of the Invisible Shield screen protectors from Zagg.
They originally designed this stuff to strengthen Army helicopter blades. Turns out, the stuff works great for screen protectors on handheld electronic devices.
Zagg makes them pre-cut for every handheld electronic gadget known to man. Over the years I have bought one for just about everything I own with any sort of a display screen. I have one on my old Palm Pilot, on my new BlackBerry, on my GPS Receiver, on my Polar heartrate monitor watch... Even if you have something they haven't already pre-cut the correct size for, you can custom order the size you need.
They're really easy to put on - a lot easier than your typical sticky screen protectors. Other screen protectors I had tried on my Palm Pilot were like messing around with a sheet of scotch tape - getting stuck to your fingers or to itself and being unforgiving about realigning it after you've already stuck it on. With the Invisible Shield, you spray it with a special solution and it won't stick to your fingers or anything else. You put it on your display, slide it back and forth to the right alignment, squeegee off the excess solution and let it dry.
Once it dries, you can't really tell it's there anymore. The website has some videos of them trying to scratch the heck out of screens of iPods with car keys, and it leaves no marks or evidence whatsoever. Like I said, I've been using them for years on my gadgets and I've had no scratches or any other blemishes on any of them, in spite of geocaching and hiking and banging the stuff on rocks.
Anyway, the reason I am writing about them TONIGHT is that when I placed an order on their website tonight, they sent me two one taken, one left - one-time-use coupons for 20% off that I could forward to friends. They expire in 30 days. If you want one of the the last coupons, drop me an email and I'll forward it to you.
