Once the smartphone screen cleaned with the wipe with alcohol and anti-static cloth, installation is made simple. The film is deposited, leaning on the button and adhesion is done alone. There is therefore no need for anti bubble squeegee.
In my case, I have this protection coupled with a strengthened hull, so I made the installation "hull mounted" to have perfect timing.
Note that the announced characteristics are met, the product is highly transparent, scratch-resistant and no fingerprints. The only thing I have not tested the resistance to strong impact (I try to avoid).
I'm really satisfied and I recommend this product.
