If you’ve recently purchased the new Whoop MG (Medical Grade) fitness band, you might be facing some serious problems. Many users have reported that their devices stopped working only hours after being set up.
Users complain about unresponsive devices
Just a few weeks after launch, the Whoop MG fitness band is making headlines for the wrong reasons. Users are posting the same complaint across online forums, Reddit, X (formerly Twitter), and the official Whoop community pages: the fitness tracker shuts down and becomes unresponsive within hours of use.
@WHOOP wow guys I was so excited to get my new MG sensor from you. After only 5 days it failed. The worst part is the absolute runaround I’ve been getting the last 24 hours trying to deal with I can only imagine is AI customer support.

Way to make a bad experience WAY worse!
After setup, the device reportedly loses all LED lights, fails to sync with the mobile app, and won’t respond to charging or other actions. This has frustrated many users, especially as the problems appear without warning and often occur within the first day.
People affected by this issue say they’ve followed all standard troubleshooting steps, including restarting their phones, reinstalling the Whoop app, and trying different charging cables — but the fitness bands still won’t respond.
Whoop responds with reset instructions
In response to growing concerns, Whoop has offered a temporary solution. The company advises users to charge their devices and perform a manual reset. To do this, tap rapidly on the top of the sensor multiple times until the side LED flashes blue. If this works, you should then be able to reconnect the band to the mobile app.
Unfortunately, this fix doesn’t seem to help everyone. Many users have reported that the LED never flashes, and the device remains inactive after multiple attempts. In such cases, Whoop has recommended contacting their customer support team for help.
It’s worth noting that some users have been sent replacements without even requesting them. This suggests that Whoop’s support team may be able to detect faults remotely and proactively resolve the issue.
Not every device is affected
Despite the number of complaints, it’s not all bad news. Some Whoop MG users say their devices are working perfectly with no issues. Still, with so many users facing similar failures, the issue does appear to be widespread. If your device has gone silent, it’s recommended that you try the reset method first. If that doesn’t work, contact Whoop support—especially since replacements are being issued free of charge in confirmed cases.
For now, if you’re considering buying a Whoop MG band, waiting until the company confirms a fix or update might be wise. Whoop has yet to issue an official statement explaining the root cause of the failures. Still, the growing volume of reports suggests this could be a bigger problem than originally expected.
