it is not the product, it is the installation process..

one quick spray with windex on the install side of the protective product (any one), install & position, then a quick spray (windex also) to top side of installed protector, then squeegee out beginning from center, in all directions..
this method works with any screen protector (or decal).
it is the only correct method to use when installing any type of decal/protective coating on another surface..

hope this helps...
