In bend tests, the dangerously thin iPad Pro turns out to be surprisingly strong.

When making its most recent iPads, Apple went all out, making them the smallest devices the company has ever made. The 13-inch iPad Pro is only 5.1 mm thick, which may seem very thin, but Apple has taken steps to avoid another bendgate scandal.

John Ternus, a senior at Apple, told Arun Maini recently that the main processing board of the tablet is in the middle, between the two batteries. A metal cover was also put over the processing board by Apple. This cover acts as a “central rib.” When put together, the design choices lead to better heat escape and much higher stiffness.

You may be wondering how long this center rib will last.

The new iPad Pro was recently put through an informal bend test by Zack Nelson of JerryRigEverything. He was pleased. Even though the screen is different from the body, the center rib seems to do a good job of protecting the tablet’s internal hardware. The iPad had a terrible failure at the USB-C charging port, which ruined the screen totally, so the vertical bend test wasn’t as forgiving.

AppleTrack’s Sam Kohl was also able to bend the new iPad Pro, but it was much more resilient than older models. It looks like the rib does its job; this is especially clear when the cowling isn’t there to protect the area.

Some laptops may not be as likely to bend as smartphones, which is good news for most people. You might sit on it by chance on the couch or in bed, but they’re too big to fit in your back pocket like a smartphone would be.

AppleCare+ is always a choice if you think you might drop your new device or just want to protect it even more. Accidental damage is covered up to an endless number of times, but you will have to pay a small service fee.

It costs $8.49 a month, or $169 if you pay for two years at once, to cover an iPad Pro 13-inch. Claims for screen damage cost $29 each, while claims for other damage cost $99 each. That’s still a lot less expensive than getting a new iPad Pro.
