As shown in this video of the brand, the effectiveness is not to question ([...]). And it's still good that we are looking at first.
That said, it has many advantages and features that make it stand out. The shell hugs the Macbook Pro 13 ". The integration is superbly successful and this is noteworthy because no one is embarrassed to 310g weight addition of one. All weak points are covered. Installation is fast because assured by a very well designed clip system. Effect bonus, the shell prevents slippage of smooth and MacBook facilitates grip. If necessary, the shell can be removed just as easily provided but is safe for not jumping If shocks.
Obviously we would have liked a softer price but considering all that it brings and the overall quality of the product, there is no photo and am completely satisfied (that is rare enough to be noted: p).
Plus: comes in several sizes to stick perfectly to your mac (13 "pro 13" retina, 15 "...) for similar prices.
