use on 2cameras and cell phone.  The cutting is fairly straight forward, but the pre-cut edge that is supposed to help with seperating the backing from the protector is not cut well so i've wasted one sheet as it ripped easily while taking off the backing.  material not durable at all.  Got scratches just by using the squeegy in the package.  Lastly, if you had to reposition it, good luck getting the bubbles (hazyness) out.  Requires too much effort to get it right.  Would not recommand it.
