Covers should protect but usually a cell phone more than once, as in my case. Right on the first day I noticed my iPhone from approximately 1 m to laminate flooring down, and there was a crack along the entire route from the headphone jack to Läutstärkeknopf.
I have had many cases for a variety of models and up to this, is never a kaputtgegangen. A great pity, at a cost of 18.00 I've expected a lot more stability.
Therefore, I would recommend this product as a pure protection against minor scratches and also because of the optics. Who should however be off and fall times to be mobile but, rather opt for another envelope!
