I'm just going to throw this out there because there isn't much info on the matter out there right now. I ended up getting the "zagg invisible shield high definition" from future shop. I had the original invisible shield on my 9900 and hated it, it really made the sensitivity worse along with it being rubbery and having orange peel like everyone usually expressed - but i had heard the newer ones were better. I just tossed it on the phone a couple hours ago, quite easy to do. I sprayed it lightly on both sides and put it down and you're able to slide it around a bit to get it aligned before using the squeege to take out the air bubbles/solution. I was happy to see that the protector is the EXACT same size as the z10s screen. At first I thought it felt rubbery but after a couple hours of drying out I'd have to say it's much better than the old ones. Not smooth like the factory glass but better than the originals. However i'm finding i like typing on it better WITH the zagg for whatever reason. It really does look crystal clear, not grainy at all. Right now there is a bit of rainbowing and micro bubbles under it that i can notice but apparently they all go away after 1-2 days. So maybe I'll get back to you on how it feels when it's fully dried/cured and it's looking mint but I can already say it's much better than their older ones. One more thing to note is that i was wondering how a protector would feel with swiping from the bottom or top since you'd have an edge but after it's on i realized you don't really swipe from the the actual phones body up, you swipe from around where it says blackberry so you're already above the edge.
Anyways i'm just kind of rambling on but wanted to give an idea on how it is. The weird thing is I called the local kiosk and asked about them and they said zagg only has the originals for the z10 and not the HD version, which I thought was weird. So I went into future shop and bought one and it says "high definition" right on it, although the packaging is different than the ones i've seen for iphones at stuff that say "HD" in big lettering as opposed to high definition. I'm sure this is the newer one though as i remember the one on my 9900 being harder to glide across the screen with my finger.
edit: about 20 hours later and any little micro bubbles or any imperfections are almost all gone. i bet by tomomrrow it'll be perfect. i've happy with it, when you tap on the screen with your nail it feels very hard/glassy rather than rubbery. it's much better than their older ones.
