Feds Say There Isn't A Single Safe 'Hoverboard' (engadget.com)
In the Consumer Product Safety Commission's letter to manufacturers, importers and retailers, it urged them to make sure the scooters they make and sell comply with the safety standards set by Underwriters Laboratories, the organization in charge of certifying that products are safe for use. According to UL Consumer Safety Director John Drengenberg, "no hoverboard has passed the certification process at this time."
The only reason UL exists is to generate income for UL. Having been through several "certification" cycles on various products, it's very clear that they exist only to run a highly-organized shakedown.
We've actually had to make our products LESS SAFE just to pass some nonsensical test that some UL "engineer' dreamt up that has no practical application in real life.
