Unlike the OnePlus One and the OnePlus 2, the new OnePlus X ($249; 16GB) isn't being advertised as a "flagship killer." Instead, it is aimed at shaking up the budget market. This compact, premium Android phone doesn't make any major hardware compromises—and it's easy to use one-handed. That makes it a rare commodity these days, but thanks to a pesky invite-only purchase system and the lack of key North American bands, the OnePlus X is difficult to recommend over rival unlocked phones like the Alcatel OneTouch Idol 3 4.7 and the Google Nexus 5X.

Design, Display, and Features

The OnePlus X has an attractive, premium build. It's essentially two slabs of glass held in place by a metal frame, similar in design to the classic Apple iPhone 4. It measures 5.51 by 2.72 by 0.27 inches (HWD) and weighs 4.86 ounces, making it easy to hold and use with just one hand. The Nexus 5X (5.79 by 2.86 by 0.31 inches, 4.8 ounces) is notably larger, while the Idol 3 (5.40 by 2.59 by 0.30 inches, 3.88 ounces) is slightly smaller, but not nearly as sleek. The glass back has a habit of picking up smudges, and feels a bit slippery in your hand, so you'll probably want to consider getting a case.
