While consumers can learn a lot about a product by reviewing specs and features, it takes hands-on experience to know how something like the iPhone 7 holds up in the real world. We’ve previously covered how Apple’s new smartphone withstands some of the most common stress scenarios, but Gizmodo recently found that the device has several less obvious vulnerabilities the tech giant hasn’t disclosed.

Here are some of the most shocking revelations, uncovered after an exhaustive, 15-minute search of YouTube.com.

Hydraulic Presses

By removing the headphone jack, Apple has been able to make the iPhone 7 significantly more waterproof than its predecessor. As first discovered by Hydraulic Press Channel, however, it appears the new model is no more hydraulicpressproof than the 6—a flaw we certainly hope they’ll address the next time around.

Drilling Hammers

Sure, the average iPhone user probably only uses a sledgehammer two to three times a year, but what about demolition workers, old-timey strongmen and avant-garde British flautists? If you’re buyer who falls into any of those categories, this video by TechRax should give you plenty of reasons to “beware.”

Angle Grinders

Apple’s new “jet black” finish has made the glossy 7 one of the “must-have” tech devices of the fall, but all that beauty comes at a price: On the smartphone’s official launch page, a footnote warns that its high shine “may show fine micro-abrasions with use.” Sadly, HaerteTest found the phone is just as susceptible to macro-abrasions, like those imposed by an ordinary diamond-bladed angle grinder.

Russian Men with Chairs

Is the iPhone 7 harder to bend? Sure seems like it. Is it so hard to bend that a determined Russian man like vlogger Sasha Shapik can’t bust it in half with a little help from his furniture? Nyet.

Axes

Pathetic.

Fire

Unfortunately, iPhone 7 users will need a peripheral to get this standard Galaxy Note 7 feature.
