The envelope was delivered to me after twenty days, but this is normal because the company has its headquarters in America. Packaging is umweltfeundlich, but in the height of the product is too small, and this is how the previous speakers had already mentioned, during delivery squashed, but what does not cause problems.
Processing & Optics:
The case looks at the advertising images of very good, but this impression does not correspond entirely to reality. Because the total envelope especially at the edges often seems not very valuable, but what should be overlooked at a price of just eleven euros actually. Nevertheless, there is also in this price range better processed cases. The clear plastic on the back is also adjusted inaccurate at the inner edge of cases, but overall can live with it. Otherwise, the product is very flat, which would appear only slightly thicker iPhone. Generally, the shell looks actually quite good. Personally, I like the fact that the manufacturer's name is on the side, this can affect the Case noble.
Practicality: & feel:
The sleeve fits comfortably in your hand and the material feels relatively well. The buttons can be operated fairly well by the hard plastic of the product and respond as usual right away. The iPhone can easily be removed with a bit of tact from the shell, but also does not sit too loosely. Between the back of the phone and the plastic section to easily captures dust, but this behaves in moderation.
Protection & stability:
I underwent the Rinke merger case more or less voluntary case tests in which the sheath portion very well. So the iPhone fell back, for example, on the tarmac of an elevation of about one meter and the smartphone did not see it as a scratch. The plastic on the back can take a lot more than it seemed at the beginning. Also at the front of the iPhone, there were during the impact with the screen facing down no problem.
Conclusion:
The concept of the envelope is indeed unique, but in processing and design compromises were made, with whom you have to live. For the Rinke Fusion Case scores at the stability and promises except a good handling adequate protection for the iPhone. So that producers had indeed a good idea, but this was thought not quite over. Nevertheless, I do not want to miss this protective sleeve and I recommend it to anyone who does not want to cover it with rubber or hard plastic, the beautiful back of the iPhone.
