Saving a couple of bucks by settling with cheaper USB-C offerings doesn’t really spell the same if you’re sacrificing quality over quantity. And apparently, that’s what the new USB-C standard is currently suffering from. There are literally hundred to thousands of offerings available from both online and offline channels, but it’s probably best if you stay away from the majority of them unless they come from first-party sellers.

Google engineer Benson Leung was tasked to check the USB Type-C cables that are available in the market to set apart the good ones from the bad, thus exposing the substandard ones that failed to meet the proper qualifications and specs. Needless to say, he’s also risking his very own Chromebook to yield the results he needed.

However, his test procedures have come to an abrupt but expected halt after one bad cable made significant damage and fried his quite expensive Chromebook Pixel as well as other devices he was using to test the device. The USB-C cord in question? It’s Surjtech’s 3M USB A-to-C cable that’s still up in Amazon.

Leung notes that the cable “complete violates the USB spec” and it has made serious damages. The review, easily a 1-star he left for the listing, states that the USB-C cable he used damaged the Chromebook Pixel and two USB PD Sniffer devices (Twinkie). He advises perusers to not buy the product under any circumstances, and Surjtech will be hearing from his end afterwards.

If you’ve been keeping up with the trend, Leung has been testing out USB-C cables on Amazon to check out the bad ones and warn users whenever the items are faulty.

“I have gotten fed up with the early cables from 3rd party vendors that so blatantly flout the specification and I want to take them to task,” wrote Leung on his Google+ plage. “You may not just get weird behavior from your devices with these bad cables… What some these vendors are doing is downright dangerous.”

If you’re an iPhone user, you don’t have to worry. Lightning cables still require Apple’s certification, and Cupertino still hasn’t adopted to the new standard for its existing iPhones. Well, not yet.
