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. ### 1/5 — Refuses to connect *2026-02-11* Very frustrated, just won’t connect to the socks….come on, do better! ### 1/5 — Heated socks *2026-01-12* 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. ### 3/5 — Connects to and runs socks, but impossible to register app or account *2026-01-04* Connects to and runs socks, but impossible to register app or account ### 2/5 — No BT Connection *2025-12-24* Did not connect to my heated socks I ordered. ### 1/5 — Unusable!! *2025-12-17* Unusable with UNUSABLE!!!! iPhone! The socks will not connect to Bluetooth! Phone fully charged, Bluetooth turned on! Unusable if you have an iPhone!!! ### 1/5 — Not with iOS *2025-12-05* This app is worthless because they do not update it. It will not work at all with the latest version of iOS on an iPhone. Why they don’t update it I do not know, but it makes for some very unhappy customers. ### 4/5 — How to fix your socks that will only pair one *2025-12-04* So if you can only pair one sock turn off your Bluetooth then wait a few sec’s then turn it back on they both will pop up ### 1/5 — App won’t find socks *2025-11-27* The app will not connect to the socks or find the device. ### 5/5 — A very convenient software *2025-11-20* Every year I buy heated socks. I like those that can be connected to a mobile phone APP. This is the fastest and most responsive heated sock I have experienced so far. It gives me convenience and I like it very much. I'm planning to buy it again. ## Frequently asked questions about SAFEIER ### What is the update frequency for SAFEIER? SAFEIER was last updated on 2025-09-12 with version 1.1.3.
