I was nervous about the installation of this product but had gathered from reading other reviews, that providing you use enough of the spray (provided) to moisten your hands & screen protector, all should go well. They were so right. You don't have to worry about placing it correctly as soon as you've put it onto your ipad, because of the moisture you are able to slide product around & into place before removing the excess moisture with tool provided. This was my first time using such a product & I found it really easy. I have NO bubbles at all. The only thing you loose is the feel of smooth gliding over glass. Don't know if the HD version would solve this but would spend the extra £'s if it did.
