Delivers what it promises - but you have to have it ??

Another positive side effect is that thus gets a much better grip the phone. The 'naked' cell phone is very smooth in my hands. With the Case you hold it very safe.

Negatives: The Case makes the phone visually clumsy and unsightly. I wonder, therefore, now, what is the real benefit. Since I have a very visually appealing N8 device purchased by Nokia and did nothing about it.
It's like a new car, the one inside out immediately slipcovers over the seats, driving 15 years with ugly seats and then bring the car with brand new seats for scrap.
With my previous mobile phone I bought after 5 years a new housing and the equipment was like new.
Better in my opinion would be a transparent and slightly thinner case, the scraper keeps the device and improves the grip.
But all these considerations only give my personal views and do not detract from the quality of the actual case. Therefore, I give full marks.
