Available through invite only, the OnePlus X is an unlocked device with high-end looks and a wallet-friendly price. Unfortunately for US customers, it won't work on a couple of important LTE bands used by GSM carriers AT&T and T-Mobile (more on that later).
The handset starts at $249 and £199 (which converts to about AU$430).
The attractive device sports a slim, elegant design with glossy glass panels on the front and back, and a surrounding silver metal trim. Though its collects fingerprints and is slippery, compared to other budget handsets, the phone is one of the best looking in its price bracket.
The X comes in two design variants. There's the more expensive Ceramic (left) version that has angled edges and is available in only Europe and India (£269), and Onyx, which has glass that smoothly curves down the edges.
Overall, the buttons stick out from the surface, which makes them easy to use by feel, but also easy to accidentally activate while it's rattling inside a bag or backpack. That's bad news when the handset turns itself on and drains its battery when you're not using it.
The X has dual-SIM capabilities, which is useful if you have more than one number or travel abroad often. It also has up to 128GB of expandable memory (a feature missing from its predecessors) on top of the 16GB of built-in storage.
Powering the phone is a 2,525mAh battery that lasted a solid 10 and a half hours during our lab tests for continuous video playback. It also has a 2.3GHz quad-core Snapdragon 801 processor from Qualcomm.
