I've had about 3 years, few seams ended up battle but without hindering the use of the product, even some edges of rubber or plastic seams left after 2 years without disturbing the use of the product. The navigation button is actually a little bit covered (up) but I did not cut the case and it does not interfere with my use of the navigation button. This case is very easy to open with one hand (magnetic closure to the appropriate resistance), the flap opens downwards which is in my opinion the most ergonomic system.
Today I bought a new copy of the product for a second E71 which I have acquired; given the state of the first case after 3 years, I think it will last at least two years under normal use.
