Case Logic is known for its robustness, here there is no shortage, I've already bought several Case Logic products (hard disk for protection) and closures, although often than open never had worries Here the design exudes quality, the strips are comfortable, within the maintenance of the laptop is good, the edges on both sides of the bottom of the bag are reinforced so that if the bag were to fall the pc will not spoil. However I have found a flaw, rain, it is his enemy, the water seeps into the bag when it rains. To overcome this problem, you can appliqyer a waterproofing spray, which will wipe out this problem without fail.
