They're out out and selling well, but that doesn't mean it's been smooth sailing for Apple's new iPhone 6 and iPhone 6 Plus.

Reports of the devices being prone to bending have been catching fire, although Apple has come out saying that it's not a real issue. The Cupertino giant has come out saying that only nine customers have complained about the iPhone 6 Plus bending since its release Friday, Sept. 19.

"With normal use, a bend in iPhone is extremely rare and through our first six days of sale, a total of nine customers have contacted Apple with a bent iPhone 6 Plus," Apple spokeswoman Trudy Muller said in an email to Reuters.

Apple says that the new iPhones have been rigorously tested and that the smartphones' have been properly strengthened. In other (Apple's) words:

"Our iPhones are designed, engineered and manufactured to be both beautiful and sturdy. iPhone 6 and iPhone 6 Plus feature a precision-engineered unibody enclosure constructed from machining a custom grade of 6000 series anodized aluminum, which is tempered for extra strength. They also feature stainless steel and titanium inserts to reinforce high-stress locations and use the strongest glass in the smartphone industry. We chose these high-quality materials and construction very carefully for their strength and durability. We also perform rigorous tests throughout the entire development cycle including 3-point bending, pressure point cycling, sit, torsion, and user studies. iPhone 6 and iPhone 6 Plus meet or exceed all of our high-quality standards to endure everyday, real-life use."

A quick search around the Internet concerning all things iPhone 6 and iPhone 6 Plus, however, seems to say otherwise. Dubbed "bendgate," stories of the new iPhones bending easily seem to spread like wildfire, even though very few came forward with actual evidence.

Even Heineken joined in on the fun, comforting Apple with a reference to beer bottle caps.

As explained in the video below, the reason for bendgate could very well be because of the iPhone 6 Plus's unibody aluminum backing. Unlike other smartphones with a magnesium chassis, the iPhone 6 Plus relies on this one thin sheet, making it more susceptible to bending, much like a piece of paper.

The exact reasons behind bendgate are still unclear, and although it is unlikely to deter potential iPhone 6 and iPhone 6 Plus buyers, you can bet it'll be on a lot of people's minds. Still, there simply isn't enough evidence to support the fact that anyone should shy away from buying one.
