Therm-ic Heat control

Batteries do not connect at all to IOS.

Batteries do not connect at all on iOS.

Works only with old iphones. Bluetooth doesn’t connect.

The app shows the units as heating even when the battery is disconnected. Can’t trust this or the battery level. For the price of the inserts, it is unconscionable that the app is so bad. Embarrassing.

Aside from this regularly disconnecting, I had to uninstall and reinstall these multiple times for the Bluetooth to recognize the signal. Great idea, doesn’t work.

I am now in year 2 with this very disappointing heater system. It absolutely never works properly. At the beginning of the day it can start burning my feet. I turn it down and it quits heating. I reset it and maybe it works for a run. Maybe. Bought with Surefoot that I think should refund the cost of the battery’s and discontinue being this reflects very badly on their boots.

Does not work at all. Total failure. Do not waste your money. Do not waste your money. Do not waste your money.

I’m surprised by the ratings and other review; my experience with Therm-ic heated clothing (and this app) has been excellent. I use the heated vest and heated socks. Bluetooth control works well and has been consistent for me. The Apple Watch app makes it easy to adjust temperature from the ski lift without having to get my phone out. I prefer to have full control over my heat settings so I don’t use the eco or motion control modes, but they seemed to work as advertised when I tested them. Be sure to upgrade your battery packs to the latest firmware if they come with an old version. And if your ski group is waiting for you to get out the door, whatever you do, don’t tell them “I’ll be ready soon I just need to upgrade the firmware in my socks.” :)

Would like to install the latest firmware on my C-PACK’s (from 12.55 to 12.57). iPhone version of software hangs with progress icon spinning; Android version returns OTA_RESULT_FW_VERIFY_ERROR. Hardware serial is B1905F0.

I love the socks but the app is pretty bad. Pause button doesn't keep it paused, it will resume within minutes despite the phone being locked with no other interactions. Sometimes top left buttons overlap iOS back button on iPhone 8+ top left notch. Reviews have been bad for years, so it doesn't look like the company plans to address any of the apps issues.
