Yes, I know, the problem is I am out of the country and VPN to my work email account is not cutting it.
But I did dig it out:

Now, I think a warning is needed, as this is not cheap. As I said before, it DOES NOT eliminate glare. It reduces it. It seems to 'diffuse' light on the screen, if that makes any sense. Under certain conditions, it works wonders (for example, I have a window behind my couch - I sit in front of it and I am bothered by the screen reflecting my face in the upper half; with this anti-glare, I get none of that).
On the other side, when the problem is a strong light shining straight into your reader (like reading under a desk-light, for example) the improvement is marginal.
Side benefits - it's easy to apply (no air bubbles like for cheaper screens) and even re-apply. It doesn't scratch and it adds protection. I don't see any differences in terms of screen readability or contrast. Nor do I notice anything different with the touchscreen.
But the disclaimer is necessary. It IMPROVES thinks, it REDUCES glare, it DOES NOT ELIMINATE glare.
Also, I still find that the best solution to glare is a good ebook light - that is, as long as you read somewhere without excessive ambient light. The doubleflex:

is a bit pricy, but it allows to shine indirect light from two angles, thus illuminating the entire screen without any direct light reflection. For many users, I suspect that's a better option than anti-glare screens. But for those forced to read in a particular spot (my couch is my couch, and I HAVE TO read there...) the above screen helps.
