We recently wrote a lengthy hands-on article about the Huawei Honor 5X smartphone, a handset whose performance, features and apparent quality surprised me, given the $200 price tag. The phone has been available for preorder for a while, but it's officially on sale now.
It appears that you can't get an Honor 5X from your carrier (at least not in the U.S.), but at $200, who cares? Subsidies have pretty much evaporated anyway, and if you aren't interested in financing your phone, you'll want something that has a reasonable price tag -- like the Honor 5X.
Huawei's push into North America (which includes the higher-end Huawei Mate 8) begins in earnest now.
Update, 2/2/16, 8:25am PT: We reached out to Huawei to confirm a detail on carrier support. A company representative told Tom's Hardware the following: "Honor 5X works on T-Mobile, along with any U.S. GSM/LTE carrier. Honor 5x also supports Band 12, but the experience will vary from carrier to carrier."
