Right here at TechCrunch we’re all for setting issues on hearth “for journalism,” however on this case the numbers communicate for themselves. If, per the researchers’ findings, the straighteners may very well be overridden to the utmost temperature of 455°F on the timeout of 20 minutes, that’s organising a chief situation for a fireplace — or at very least burn injury.
