Whoop’s new MG fitness bands have suddenly stopped working for many users

• Early buyers of the new Whoop 5.0 and especially the medical-grade MG are reporting widespread device failures shortly after receiving them, with devices becoming unresponsive.

• Despite offering troubleshooting steps, Whoop appears to be proactively sending replacement units to affected users, suggesting a potential quality control issue with the initial batch of the new MG trackers.

• The significant number of complaints online points to a major blunder for Whoop, with speculation that the company is now shipping replacements from a potentially corrected production run.

The launch of Whoop’s latest Whoop 5.0 and the Whoop MG (medical grade) has been marred with complaints about the wearables failing for a significant portion of early buyers.

For those unaware, Whoop wearables are primarily known for their fitness-tracking features, but they also offer robust health monitoring capabilities. With the new Whoop MG, the company is expanding its health-focused features, complete with blood pressure insights and “clinically-accurate ECG readings.”

The promising debut, however, is now being overshadowed by reports of the new wearables dying.

This isn’t an isolated incident. A large number of users have aired their grievances online, with issues primarily affecting those with the MG model, as highlighted by TechIssuesToday.

It appears I’ve got a dead MG. It arrived two days ago with 98% charge. Battery pack seemed charged and I used it to initially get the MG into pairing mode. After ~1 day of seamless operation I woke this morning and noticed it hasn’t synced up overnight and now nothing I do can get it to wake up or show any LED lights. Battery pack appears fine.

Users’ MG devices reportedly stopped working without any warning signs, remaining unresponsive even after being fully charged.

The company is actively issuing replacements

User reports have made their way to Whoop’s community forum, and although the company is yet to share the root cause of the issue, it seemingly is offering replacement devices to those affected.

“We’ve noticed your WHOOP may not be syncing as it should. We have proactively sent you replacement WHOOP right away,” reads the company’s email to an affected user. Several others confirmed that they’re being sent replacement units too.

The company also shared some troubleshooting steps, which included checking the battery pack, charging the Whoop MG sensor for at least 15 minutes, force restarting the device, and pairing the device again. I have yet to see a single Whoop MG case where any of the troubleshooting steps offered relief. If you’re facing the same issue with your new Whoop, submitting a support request for a replacement device might be your best bet.

This is a major quality control blunder on Whoop’s part. It is plausible that an early batch faced some mass manufacturing defects, and the company is now shipping replacements from a newer batch, though that’s just speculation.
