McDonald’s was trying to get a few steps ahead of the criticism that Happy Meals run completely counter to health and fitness by offering fitness trackers in their kid-focused food. Instead, they got a rash of complaints that led the fast food giant to immediately stop the campaign and issue an apology.Turns out the brightly-colored Step It! Activity Band – a wristband that could track just how much little McDonald’s customers were moving and blinked according to speed – were causing skin irritations. The tip came from mom Casey Collyar, who posted on Facebook a picture of her child’s burn from StepIt. Her post was shared more than 100,000 times.The promotion was supposed to last four weeks at every location in the US and Canada, but lasted just a few days after the complaints started rolling in.“We are voluntarily removing the Step It! Activity Band Happy Meal toys in our restaurants in our United States and Canadian markets. It will no longer be offered as part of our Happy Meals. We have taken this swift and voluntary step after receiving limited reports of potential skin irritations that may be associated from wearing the band,” Terri Hickey of McDonald’s Global Communications said in a statement.Hickey did not respond to request for more information, such as the manufacturer of the product, nor how many complaints McDonald’s has received. Mashable reported the back of the band only indicated it was made in China.
