Surefoot Winterheat

My wife and I both bought the 3400’s, so it’s not just a defective pair. We both agree they just don’t get anywhere warm enough that they make a difference. Surefoot liners are amazing and worth the extra $$$, but these heaters have been a disappointment. Also, the instructions seem outdated, and the UX in the App Store doesn’t match the actual app UX. Renaming the heaters to something unique doesn’t stay, you also have to rename them everytime you turn them on, which is an idiotic experience.

My Atomics gave me an aggressive stance and edged well but were slightly uncomfortable by the end of the day. OTOH, I forget that I have the Surefoot boots on because they are so comfortable. The neatly integrated liner heater is a good idea and the Killington SF shop stood behind the product (thx Chuck) when I had an issue with one. Good product and good service.

As I mentioned in a review 2 years ago some of the buttons on the main screen overlap and are unusable. How about reducing the space consumed by the inactive logo at the top to make room for important functional parts? I needed to replace one battery and found it impossible to do so, had to delete the app and start anew. Also wish each battery could have separate control for heat level. One of my original upper elements was replaced with a sole part and I now have to settle for a balance where one is too warm and the other too cool. Overall it mostly does the job but still needs some improvements.
