The offer comes from yapper_wireless, a top-rated eBay seller with a positive feedback rating of 98.6%. Interestingly, this is the same seller that had previously offered the 32GB version of the Nexus 5X at $379, down from its usual retail price of $399.
At this point, we'll have to remind you that Nexus devices do not come with microSD card slots, which means that 16GB of storage is all you're going to get. Many users will have no problem working around this limitation, but please bear in mind that high-quality videos and modern, graphics-intensive mobile games will eat through 16GB of storage (that's before the Android OS is installed) in no time.
Compared to the Motorola Moto X Pure Edition, the 5.7-inch phablet which appears to be the main competitor for the Nexus 5X in the US, the latter is by far more compact, featuring a 5.2-inch IPS panel with a resolution of 1080 by 1920 pixels.
Like with all Nexus smartphones, one great thing about the Nexus 5X is that it comes with a stock Android version (6.0 Marshmallow at the moment), which usually runs smoother compared to customized implementations. Furthermore, you can expect to receive timely software updates from Google all the way towards the end of 2017, maybe even longer.
On the hardware side, the plastic construction of the Nexus 5X is no match for what premium smartphones like the Google Nexus 6P have to offer, but then again, this is a $312 smartphone we're talking about. The Qualcomm Snapdragon 808 chipset that's at the heart of the Nexus 5X is paired with just 2GB of RAM, which may be a turndown for some. However, in our detailed Google Nexus 5X review, which is a must-read if you're planning a purchase, we've found that the device runs impressively smooth despite the fact that it doesn't feature flagship-level hardware.
Other strong points for the LG-made Nexus 5X are a responsive fingerprint reader, a 12MP primary camera with laser-assisted focus, as well as a pretty good recharge time.
If $312 seems like a good price for the Nexus 5X to you, then you'd better hurry and take advantage of this deal. Only limited quantities are available, and chances are that the stock won't last for long at this price.
