My goal is maximum protection with minimal weight gain. This bumper gives substantial protection to my iPhone 6s plus from drops (guaranteed up to 11 feet) while protecting the edges from chips and damage. Because it's beveled to the edge of the phone it also helps protect the glass screen in a drop but not on a direct hit to the screen (nothing does except a screen protector). Most important it adds virtually no weight to the phone while offering the same protection as the heavy cases that more than double the weight of the phone (my brother has one of those that I checked out first). I have a screen protector (it is HD glass) and have ordered a rear protector (HD glass also) to prevent scratches to the rear of the phone. To go even lighter, I may switch to polymer protectors (even more protective than glass protectors)for the screen and rear.
