    AWESOME TOASTY TOES!
  

*by G***N on Reviewed in the United States on 28 February 2022*

I am a skier and have struggled with cold toes my entire life. Like white toes, they go numb, I need to stop skiing because they hurt so much. For years I've used the disposable heating packets and they've worked ok but my feet still sometimes get cold and I needed to stop skiing. I also tried cheaper electronic socks but those literally electrocuted my feet (you get what you pay for!) So, even though it's a pricey system, I finally decided to bite the bullet and buy these. I used them skiing last weekend and ...WOWZA!!! They really work!! For the first time EVER, my feet were toasty ALL DAY LONG! It was between 5-15 degrees where we were skiing and I had them on level 2 or 3 (they go up to level 4). They lasted the entire day (instructions say level 3 will give you up to 7.5 hours). The installation seemed slightly confusing at first but I just pulled up a 6 minute YouTube video and someone walked me right through it. Easy Peasy! I highly recommend these to anyone wanting to stay warm all day -- they TOTALLY work!! Thanks Hotronics!

    Customer service responsive when I needed them
  

*by M***H on Reviewed in the United States on 23 December 2021*

Yes, they're challenging to install, but better than paying double to have it done for you. When one battery pack mysteriously stopped turning on, customer service got right back to me, very quickly. Working now. Would buy again. Skiing today! WOOT WOOT!
