Well, I installed the Wrapsol screen protector today.
First off, it is scary to be using water on the PRS-600 screen. I did a full shut-down before proceeding and tried to be careful. Back on and working now, whew!!

(As a side note, when I turned the Reader back on I could no longer access one of the library books I had on there.)
Following the instructions I got the Wrapsol on okay. No bubbles, just an adhesive haze they claim will go away in 24 hours. I certainly hope so!
I can tell you that the glare is worse. Specifically, the lights above my chair now bounce back as if from a mirror. I can see their complete reflection, instead of the hazy glow I got before. (Sorry no before and after pictures.

)
As long as the "adhesive haze" I mentioned clears up, I will keep the Wrapsol on, because it will protect from scratches when I use the stylus or my fingernail. It appears not to affect screen clarity. But if you are looking for anti-glare, I would say keep looking.
Good luck!
