Hailed as a flagship-killing bargain, the OnePlus 2 is just OK and not even that cheap.
There are already four million people on the waiting list, and invites—not for the phone, just the right to pay $329 for it—are selling for upward of $200 on eBay. … It's a good phone, and most people who buy it will probably like it. But you can buy better phones, and you can buy cheaper phones. In the case of the Moto G, you can buy a cheaper phone that's better in a lot of ways. The OnePlus 2 isn't for the hardware-obsessed, it's not for the price-obsessed, and it's not killing any flagships now or ever.
[flagship-killer claims are] pure marketing fluff … a utilitarian device that's more business than party, but is still pretty great
Engadget says you should hold off:
The OnePlus 2 is worth your cash if you're looking for a capable, powerful Android phone on the cheap, but you'd do well to wait a few weeks to see how the competition stacks up.
The WSJ likes the price.
If you don't need the absolute cutting edge and you don't use mobile payments, the OnePlus 2 is a phenomenal bargain.
The phone, which you can only buy from the company's website, ships unlocked and can be used on either AT&T or T-Mobile's networks in the U.S. You can't buy a better Android phone for $330.
Ars Technica weighs the good and bad at length.
Even if you want a OnePlus 2, you'll probably have a hard time buying one.
