Generic Name: Home Air Massager — Product Name: Doctor Medmar Dm-4s

Recall Summary The Doctor Medmar DM-4S home air massager is being recalled due to a defect in Boot A's air intake port (pink), which can separate from its weld during use. When this happens, air leaks from the boot and causes the device to stop with an error instead of reaching its intended pressure setting. No serious health injuries have been reported so far, and the manufacturer does not expect any severe health risks from this issue.
