NuGuard KX will guard your iPhone 6s/6s Plus

NewerTech's NuGuard KX protective cases for the Apple iPhone 6s and 6s Plus resemble Apple Smart Cases on steroids with their one-piece design. However, they're thicker than the Apple product. Due to this, and other features, the NuGuard KX is more protective than the Smart Case, but does add more bulk to your smartphone. 

The NuGuard KX case (I tested the one for the iPhone 6s Plus) boasts X-Orbing gel technology that's designed to absorb and evenly distribute kinetic energy. The outside of the case — the grip shell — has a cross hatch design that helps prevent the iPhone from slipping out of your hand. 

The NuGuard case is easy to install; it snaps into place. Once on, it offers easy access to all buttons and ports on the Apple smartphone. You’ll be able to connect small- to medium-sized headphone and Lightning plug accessories; however, larger ones may not fit. Also, while the included button protection is handy in preventing accidental power-ups/power-downs, it slightly impedes the iPhone's tactility (especially the Sleep/Wake button).

How tough is the NuGuard KX? NewerTech says, in their tests, iPhones dressed in the case have survived 15-foot and 20-foot drops onto concrete, as well as a 131-foot drop test from an on-site wind turbine. I'm not going to drop my iPhone 6s Plus from 15 feet, much less 131 feet. 

One caveat: I do wish there was a belt clip option available.

The NuGuard KX cases come in a variety of colors including black, blue, red, and "midnight." The iPhone 6s case costs $29.99; the iPhone 6s Plus version is $33.99.
