Therm-ic Heat control 4+

I have used this for two days with my new batteries. It works fine when I originally pair them, but then at lunch it says the batteries have disconnected, even though they have never been more than 5 feet from my iPhone XS. Had to reconnect and reset them at lunch both days and then when I got back from my ski day today, they had disconnected again. GRR, great idea, very buggy execution.

Update: contacted customer support. Responded quickly. Had to do a hard reset of the batteries. That resolved the issue for me. Working again as it did before the update.

Worked great all last year. Latest update a few weeks ago broke it. Won’t reconnect to units after you turn them off and back on unless you delete them from the app and re add them again. Basically the blue tooth function with the app is effectively now broken. Disappointed. Now having to use them manually like the non Bluetooth version.

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.” :)
