User Reviews

Users largely praise the socks for comfort and effective heating. However, the SAFEIER iOS app suffers from pervasive Bluetooth connectivity problems, compatibility issues with newer iOS versions, and poor support. Several reviews note the app sometimes cannot pair or control the socks, and updates can remove key functionality. Some users report occasional positive performance when it works, but overall reliability and support remain the main drawbacks.

Pros

Comfortable, well-heated socks.
Heating design avoids uncomfortable wires.
When the app connects, it enables convenient control of the socks.
Some reviewers find the product fast and responsive when it works.

Cons

Persistent Bluetooth connectivity issues: pairing often fails, connections drop, and devices may not be found.
Incompatibility with latest iOS versions and lack of timely app updates (iOS 18, 18.2 can break functionality).
Lack of customer support and refund options (no contact options, slow or no responses).
App loses control screen after updates or provides limited controls (reduced usability).
Registration or account setup can be inconsistent or impossible.

Recent reviews

I suffer from neuropathy and sometimes especially in the winter time. My feet feel like they’re freezing so when I put these electric socks on, it helps my neuropathy. Unfortunately, I am having trouble with the app. Find my devices, but it doesn’t connect them. But they are very comfortable socks, almost like compression socks.

Very frustrated, just won’t connect to the socks….come on, do better!

Run away from this product, it is absolutely terrible. Won’t stay connected to Bluetooth, sometimes one sock works, for an hour. Eventually neither sock will connect. Have deleted app and reinstalled twice. Works for an hour or less then disconnect from Bluetooth again. And they provide no way to contact them to get your money back. Huge mistake.
