BlendJet is recalling about 4.8 million of its portable blenders over laceration and fire hazards after receiving dozens of reports of injuries, federal regulators said Thursday.

BlendJet 2 Portable Blenders can overheat or catch fire, according to a notice from the U.S. Consumer Product Safety Commission, and their blender blades can break off during use.

There have been 329 reports of blades breaking during use to date, the CPSC said, as well as 17 additional reports of overheating or fires that resulted in about $150,000 of property damage claims. The company has also received 49 reports of minor burn injuries and one reported laceration injury.

Regulators urged consumers to stop using the recalled blenders immediately and contact BlendJet for a free base unit replacement. To receive the replacement part, customers will need to remove and cut up the base’s rubber seal and email or upload a photo using BlendJet’s website.
