URGENT: MEDICAL DEVICE CORRECTION
Fisher Wallace Stimulator Model #: FW-100
Dear Device User,
Fisher Wallace Laboratories, Inc. (“Fisher Wallace”) is voluntarily correcting the labeling for the Fisher Wallace Stimulator, Model #: FW-100, due to concerns that AA batteries may overheat if they are incorrectly installed. If AA batteries are incorrectly installed into the device (installed backwards), the batteries and battery cover may become hot, possibly leading to pain, discomfort, irritation, or burns if they are touched. We have no evidence that there is a fire risk.
Fisher Wallace is aware of thirteen (13) complaints related to excess heat of the Fisher Wallace Stimulator battery cover, recorded as thirteen (13) medical device reports (MDRs) that relate to this issue. Of these thirteen (13) complaints, two (2) customers complained of burning their fingers when touching the batteries and/or battery cover, but did not require medical intervention.
Our records indicate you have received the Fisher Wallace Stimulator model FW-100. The device model/type may be identified by reviewing the device’s back label field titled “Model” where the specific model (e.g., FW-100) of the product is described. Affected serial numbers include 2020200000-2022278000. The serial number can be found on the device’s back label field titled “Serial Number.”
See below example picture:
Risk to Health:
To avoid potential excess heat of the Fisher Wallace Stimulator FW-100, users are instructed to ensure that the AA batteries that power the device are inserted with the correct orientation, consistent with the diagram found in the battery compartment.

We have no evidence that there is a fire risk.

How to recognize that the device is failing:
If the Fisher Wallace Stimulator FW-100 exhibits excess heat, the user is instructed to turn off the device, wait until the device cools, and check the battery compartment for any sign of damage, such as but not limited to a burning smell or discoloration.
