The film is rigid so you can try several times without worries, the film remains intact and does not adhere immediately when it is placed.
The shape is perfect, there is a little less than one mm on each edge to apply with ease.
If the phone and been thoroughly cleaned prior to application (glass cleaner for fingerprints and micro fiber provided for finishing, dust etc ..) and it is applied with a stiff card (CB, vital card ...) the film does virtually no bubble and some that it could drag on the edges leave without worries using the rigid board.
Once installed you can not see it, we must dwell on the phone to see the film edges.
The touchscreen responds perfectly, the touch is soft after a few minutes of use, the camera and the light sensor are not hidden.
Fast shipping, great product, easy installation even for novices I highly recommend!
