Ace Case Lenovo 300/500 E/W Gen 3 Com – Black – Drop Protection Best-in-class protection We believe good enough isn't good enough So, we make it a point to go above and beyond-even in the way we test our products. Military standards for drop testing require that a product like Ace Case be able to maintain all operating functions after dropping 26 times from a height of 4 feet. We subjected Ace Case to our own extreme testing at 6.6 feet. It passed. And that calls for the best drop of all...a mic drop. If you're looking to make a case all your own, the choice is clear We use completely transparent materials for our top & bottom panel that allow for asset tagging, barcode scanning, or simply let the beauty of the device shine through. But there's one more thing we want to make perfectly clear: this stylish case still provides the maximum level of protection for your digital fleet. Additional features Easily convert from laptop to tablet mode Quick and secure installation Thin enough to fit in most charge carts Allows access to all ports
