I haven't. I would probably try to if it wasn't for a few wacky numbers by the end of 2 weeks. I prefer not to wear a sensor if it even acts a little bit funky after the suggested wear time. Also, I do have an issue with the adhering to my skin even with using both skin tac and a durable sticker tape over it. Another issue would be that the longer the sensor is on, the more irritated my skin will be after removing it.
