I have an invisible shield on my EVO. It works great. I can throw my phone in my pocket with keys, drop it, etc and dont have to worry.
I used it on my PRE ( same one lasted an entire year)
And also had one the year before on my Instinct.
They are costly, but as long as you install them right with no air bubbles and dust/hairs they will last as advertised. The evo one is EXTREMELY EASY to apply since its just glass.
I dont go for the full body IS KITS because they eventually will peel on the corners ( not on the screen) , just the screen protector + a silicone sleeve does the trick for me. At least until they make an Otterbox for the EVO then I will get that
**** NOTE TO ALL OF YOU "ITS GLASS" posters.. Keep in mind Glass has a point of impact, if you drop it even a few feet if it lands the wrong way or lands on a sharp corner of a table it could be a cracked screen. With an invisible Shield you increase the density and give it a thin cushion of polymer film to "dent" or absorb the impact versus the glass itself. Thats something to consider, the material from the invisible shield really is great stuff, its nothing like the cheap precut plastic adhesive protectors you buy on ebay or even the sprint store.
I actually work for SPRINT, and i swear I dont work for invisible shield, but their products really are superior to the made in china crap that comes from other vendors.
