OnePlus One

Digital Versus | Sofian Nouira

It's hard not to like the OnePlus One. It's pretty close to perfect, and once you add price to the equation, it's a tough one to resist. The only problem is its by-invitation-only purchase scheme, which means you'll have to be patient-or lucky-to get one.

But it really does have 'it' - that combination of good design, reliable performance and value for money. The Nexus 5 has it, so does the smaller Moto G. But now the OnePlus One has surpassed both and takes its place as the king of the budget flagships.

There are a few little issues, but nothing that should stop 99 per cent of people from buying one. It's just a pity actually obtaining one is such a pain - but that almost makes it a more alluring device.

Arguably the OnePlus One is the coolest smartphone around. The 5.5in Android device runs refined CyanogenMod software...The real downside to this smartphone is its local availability; buying one requires an invitation. Otherwise, it dwarfs even the Nexus 5 on both value and performance.

... it is difficult not to recommend OnePlus One. It is not just a performance powerhorse with hardware specifications, but also a very well-rounded offering with equal emphasis on ergonomics and form factor.

TechRadar | Jon Mundy

The OnePlus One offers Samsung Galaxy S5 performance for less than half the price. If that doesn't make it attractive it also has a customisable OS and a 1080p display. There are a few downsides, but overall the OnePlus One is amazing value for money.

The OnePlus One is not a perfect phone, but it competes with phones twice the price without serious caveats beyond limited 4G support. And for that reason, it's one of 2014's best phones.

Engadget | Brad Molen

It doesn't make sense that the OnePlus One should be this inexpensive. It looks elegant, feels solid and performs smoothly, and it doesn't show any signs that it's a first-generation product from an unknown company.

But at the price the OnePlus One is an amazing deal. It's a flagship smartphone for a mid-range price.

Wired UK | Dave Oliver

This is a seriously impressive phone, especially at this price. There may be a few bugs in the software, but we didn't come across any major issues, and in terms of capability, appearance and even distinctiveness, it's right up there with the best of them.

Android Authority | Joshua Vergara

We had a hard time finding anything to fault with the OnePlus One. Top of the line performance, great build quality, and arguably Cyanogen's finest work. Yet it remains elusive – for now.

Mobile Syrup | Daniel Bader

The OnePlus One is a remarkably good smartphone. With the OnePlus One, a user not only saves money on his or her monthly plan, but manages to avoid carrier pre-loads and slow software updates.

NotebookCheck | Daniel Schmidt

OnePlus delivers a really good smartphone with the One that calls itself Flagship Killer - and not without reason. We give a plus point for the outstanding performance-price ratio, which remains unmatched.

YourTechExplained | Ben Schoon

Overall, the OnePlus One is an awesome device. It doesn't try to do everything, but also doesn't compromise in many key areas.

TechnoBuffalo | Brandon Russell

When OnePlus calls the One a flagship killer, the company isn't exaggerating. It won't outsell any of the most popular Android devices around, and it won't take down Apple's mighty iPhone. But it will slowly win people over, like me, because of its fantastic design, great OS and bottom-dollar price. That's about all you can ask for in a handset, and I can't wait to see what OnePlus does next. It's just too bad actually getting the device is so darn hard.

AndroidPit | Loie Favre

OnePlus One is a top smartphone with a shamelessly low price.

Know Your Mobile | Andrew Williams

The OnePlus One is a great phone that sells at a frankly ridiculous price. We thought the Nexus 5 and LG G2 were good value – they still are – but the OnePlus One is on another level.

Tom's Guide | Michael Andronico

The OnePlus One is a gorgeous, powerful flagship phone that sells for a budget price. The handset's rich HD screen, sharp camera and stunning battery life all hold their own against popular phones.

If you can stomach getting in line to buy one of these phones – at present you need an invite and they're not too easy to come by – the OnePlus One is a real bargain.

Neowin | Timi Cantisano

Overall, this is a beautiful and powerful device, that runs an excellent build of Android created by the CyanogenMod team. Although it might not be perfect and better devices will undoubtedly emerge over the course of 2015, the OnePlus One will still have heavy appeal due to its value and its ability to hit the "sweet spot". I would feel confident in stating that this is the best Android device released in 2014.

NDTV Gadgets | Jamshed Avari

Calling this phone a "flagship killer" is an overstatement, but only a very, very tiny bit. It certainly has the goods in terms of specifications and raw power, and if that's your main concern then you can save a lot of money by forgetting about Samsung, HTC and Sony altogether.

CNET UK | Aloysius Low

Though it's one of this year's better Android phones on paper, the OnePlus One isn't for everyone, nor is it readily available.

Digital Trends | Jeffrey Van Camp

OnePlus One is a huge bargain on paper, but we don't recommend it. This phone is chock full of annoying bugs and issues, and customer service isn't up to par.
