Patented Crumple Zone Corners use a unique internal structure and contoured shape to create maximum shock
absorption in the corners of the case, shielding the most vulnerable areas of the device from impact.
The BX²™ Edge Case for Surface Pro 4 is the ultimate pairing of protection and functionality. It is constructed using a co-molded design that uses both rigid and tactile materials, impact-dispersing Crumple Zone corner construction, and BX²™ Xtreme Foam to achieve maximum drop protection. Brenthaven designers focused on the functionality of the Surface device, ensuring that the Kickstand, Type Cover, and other features of the Surface are all fully functional when the BX²™ Edge is installed. To maximize the protectiveness of the Type Cover when the device is not in use, a small tab at the top of the BX²™ Edge enables the user to tuck the Type Cover into the case, creating 360-degree protection in the event of a drop. The BX²™ Edge has been drop-tested from six feet to exceed military standard MIL-STD-810G.
This is my favorite and my choice to purchase for next year. This case had the best combination of features and design for what I wanted. The BX2 line for Surface Pro 4, Surface 3 and iPad Air / Mini is the first time I think Brenthaven has entered the market of protective shell cases. This case is made of a rubberized plastic that is much more flexible than all the other cases I tested. This means that rather than cracking it will just bend. Cracking was the issue I had with my Surface Pro 3 cases so it was a major concern to me. The BX2 comes with a tether for the stylus pen which is something Toshiba and Lenovo used to do but most Tablet PC makers don't do anymore. It also has a storage location for pen. The hook to hold the keyboard closed is a take it or leave it feature. The biggest flaw in the case design is it totally blocks access to the MicroSD port. We don't use MicroSD much so I can live with it but if you use it all the time this case may not work for you.
