This is the only shell available for E2, so no choice. Luckily it fits perfectly and the side roughness is well in hand. Aute note does not cover the two ends, and does not protrude slightly on the front, damage would have been much more effective, the material is too hard But hey better than nothing, the 3 films are seals perfect. Too bad the MOCHA mark is not interested in ACER, as their silicon shells are perfect and much better shock absorption.
