Because the microfibre cloth and plastic "flattening" tool were not provided, this product essentially became useless for me. I tried putting the guard on without them twice and I ended up with lots of bubbles on the screen so I had to remove it.
I didn't want a flip cover for my S4 so I bought this instead. It protects the body and screen extremely well and it looks classy and yet understated.. It is very nice to the touch and doesn't slip either.
