 Hatch Baby says the white plastic housing around the adapter can come off while it's being unplugged from an outlet, leaving the prongs exposed. They've had 19 reports of faulty housing and two minor electrical shocks. An alert from the Consumer Product Safety Commission says the recall impacts nearly a million units sold with Hatch's REST first-generation sound machines in the U.S. and Canada from 2019 to 2022 at major retailers.
