I just installed the InvisibleShield for my 17" MBP. It is quite easy to install after being generous with the ShieldSpray which lubricates the adhesive. At first I was afraid of getting liquid all over the computer, but I kept a terrycloth around and it worked out. I just have to complain that the pieces for the bottom don't match up too well and the wrist covers don't cover the parts above and below the touchpad I already had TrackFilm, but the InvisibleShield works better for the button, but so as well for the touchpad. I tried my best to get rid of the air bubbles, but some appeared after it dried so there is no way to get rid of them short of removing the shield or using a razor (I will do neither). The top is a whole piece so it was difficult to align perfectly. Appearance wise, it's pretty good, but like I said some pieces aren't cut to fit that well. For example the battery is round at the button, but the shield is cornered so the the manufacturer took a shortcut and just made the shield a bit shorter than the whole surface. Another issue is the screw holes are now covered. I've been told I'm suppose to punch them out with my fingers, but as much as I try they won't come out. Apart from the appearance, everything is in order. However it feels my computer is bit hotter than before, but it feels cooler on the button. I think the shield as acting as an insulator which is good I guess since I won't burn myself. The bad part is the temperature will be higher, but that's what fans are for.
