We’ve tested it on most every public toilet sensor type, and yes, we’ve found that they work on all the models out there. However, if you find that your Flush Hush does not affix or fully cover a public toilet sensor out there, please snap a photo and send it to us at mamas@tinyundies.com and we will find a solution! If the sensor has two possible “eyes” and you’re not sure which to cover, simply use BOTH included FlushHushers, side by side, to keep the sensor from seeing you and/or your child.
