I can't say wheter if the bumper and the screen do the job or not because in this given time, my phone, has not been victim to any impact that would rightfully test this product. But, to the look of it, it does seem very protective. I was not capable of installing the screen with the proficiency and results I would have wanted to reach. I was not able to set the screen symmetrically in respect to the cutouts (camera, speaker, home button). I do not doubt it is possible but I can say it was too hard for me to do it without losing my patience. Nevertheless, I believe it was installed with plausible results. The bumper is fairly easy to install and removal requires just a little bit more pressure than what I would care to apply on my phone. Overly, it makes me feel assured that my phone is protected, it is very slim, it is quite price worthy, they ship world-wide, and have excellent customer support.
