A spokesman for the IT giant told CNBC that it had selected "high quality materials" and that the new models have been through rigorous tests.
CNBC editor Jon Fortt tweeted:

Apple has apologised for the rotten experience reported by the buyers of its latest iPhone.
Some people who raced to get the iPhone 6 Plus last week have since complained that the smartphone bends out of shape in their pockets.
Widespread user discontent followed about problems with Apple's upgrade to its new iOS 8 operating system, prompting the company to pull a release that had been issued to fix existing errors.
ITV News Consumer Editor Chris Choi reports on a difficult few days for the tech giant.
Computer giant Apple has apologised after an update of i.O.S.8.1 left some iPhone6 users without service and other problems.
They said: "We apologise for the great inconvenience experienced by users, and are working around the clock to prepare iOS 8.0.2 with a fix for the issue, and will release it as soon as it is ready in the next few days.”
They added that they had a workaround for iPhone 6 and iPhone 6 Plus users which enabled them to restore the phone service and Touch ID functionality after updating to iOS 8.0.1.
They said: "Affected users can reinstall iOS 8 through iTunes. For more information visit http://support.apple.com/kb/HT6487."

The bending rumours are unlikely to put any die-hard Apple fans (or many others) off from buying their new iPhones but if you’re worried, it seems sensible to exercise a little common sense when using it.
As Rik Henderson wrote for Pocket Lint: "Don't put a 5.5-inch superthin phone in your back pocket, no matter whether it is made by Apple, Samsung or any other manufacturer.
“You wouldn't put your glasses in your back pocket would you? And they probably cost less.”
Angry owners have claimed the new iPhone 6 Plus has bent in their pockets just days after buying them in what has been dubbed 'Bend Gate'.Read the full story ›
Apple has sold more than 10 million of the new iPhone 6 models in the first weekend - a record total that could have been higher if more stock had been available.
Tim Cook, chief executive, said that sales of iPhone 6 and iPhone 6 Plus, had exceeded the technology giant's expectations. It took more than four million pre-orders for the new smartphones, which boast larger screens.
"While our team managed the manufacturing ramp better than ever before, we could have sold many more iPhones with greater supply and we are working hard to fill orders as quickly as possible," he added.
Apple sold five million iPhone 5 handsets, four million iPhone 4S models and 1.7 million iPhone 4 units during the first weekend.
Actors Tom Hardy and his fiancee, actress Charlotte Riley, along with Mamma Mia! star Dominic Cooper and Doctor Who's Jenna Coleman were among the thousands who picked up the new iPhone 6 today at Apple's Regent Street store in London.
Reports suggested that some 5,000 people queued outside the Apple store on Fifth Avenue in Manhattan, while outlets in the 10 countries were the device went on sale today were all busy with early adopters. Last week Apple reported a record four million pre-orders for the iPhone 6.
Most technology writers have praised the new smartphone. Stuart Miles, founder of gadget website Pocket-lint, said: "Ultimately the two new iPhones will be very successful because while Apple doesn't deliver new tech it delivers it in such a way that consumers want without getting bogged down with tech specs.
"Apple's attention to detail has a huge knock-on effect in making other manufacturers continually up their game."
A picture of Apple fans queuing outside the technology giant's Covent Garden store today waiting to buy the new iPhone 6 has sparked an unexpected online row.
The Independent's report is headlined "There is literally not a single woman in this iPhone 6 queue", but Rhiannon Williams, the Telegraph's technology reporter, says that claim is "untrue".
The story does acknowledge that there were some women in the queue, but it is certainly difficult - if not impossible - to see any in the picture above.
Meanwhile, a survey of 750 women and 1,250 men has claimed that women are more avid smartphone users than men, with 18% of women checking their devices at least once an hour, compared with 13% of men.
The first person to buy a new iPhone 6 in London said his first priority with the new phone would be taking a selfie.
Jameel Ahmed, 26, and his friend Sam Sheikh, 27, were the first two technology fans through the doors of the Apple store in Covent Garden to buy the new iPhone 6 and iPhone 6 Plus handsets.
Mr Ahmed said he was "really excited", adding: "I'd like to open it and take my selfie. It's a challenge with my friends that I'll have the iPhone first."
The iPhone 6, with a 4.7 inch screen, and the 6 Plus with 5.5 inch display, went on sale in nine countries and the UK today.
EE said that customers who pre-ordered handsets through Phones 4u, which went bust on Sunday, would still be able to get them in its stores if they had their receipts.
