The case provides for the Lumia 635 is very poor, and at the time I made the acquisition, design of it seems to be the best answer to the need for protection, ease of opening, simplicity (guarantee). The clasp of the valve through claw is a very good solution. its simplicity is a guarantee of greater sustainability than other clasp system, which in my experience are aging badly incessant daily demands. Certainly, the claws on the 4 corners significantly weigh down the aesthetics of the whole but they need to recognize two significant advantages: - Smartphone protection at the most critical place in case of fall - Leave visible slices of Nokia, this qu'apprécierons those who want to easily find their Lumia 635 with the bright color of its hull. One regret: I find it unfortunate that the manufacturer did not propose colorful variation in accordance with the colors of the Nokia, but I would understand perfectly that industrial constraints (additional cost, given the aging, health permits etc ...) have justified the choice of the manufacturer to stick to black.
