(CBS NEWS) -- At least 22 people are suing the maker of the NutriBullet, claiming the device malfunctioned and caused serious injuries, including burns and lacerations. It's billed as a high-speed appliance that can pulverize foods better than an ordinary blender, reports CBS News correspondent Mireya Villarreal.

"The secret of the NutriBullet is its powerful, 600-watt motor," an advertisement claims.

But some users of the NutriBullet say the device is also dangerous.

Sheryl Utal said she used her NutriBullet daily for years to make smoothies – until one morning it exploded after about 20 seconds, causing second-degree burns.

"It just came flying out all over me, all over the kitchen, the ceilings, the walls," Utal said.

She said her arms felt "on fire."

"And it was on my chest. It also had hit me in the face as well," Utal said. She is one of the people now suing the company.
