### ⭐⭐⭐⭐⭐ AWESOME TOASTY TOES!
*by G***N on February 28, 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!

### ⭐⭐⭐⭐⭐ Excellent product
*by K***R on March 24, 2023*

I have been using these heaters for 2 seasons, all Colorado skiing. Days have varied from single digits to above 40 degrees F. It took more time than I expected to install them, but there are a few very good videos that explain in detail how to install them correctly. In all cases they have kept my feet warm, and it's easy to change the temperature as the day warms up. I've only broken the clip holding the battery once during a fall. However, it was very easy to replace the clip. I now carry a spare clip in my pack when skiing.

### ⭐ terrible quality- crazy price for a battery pack and cheap wires that break constantly
*by D***. on February 2, 2025*

read the headline. Such a joke, last a season or two before you have to replace the insert and they stopped making them so you're left with $250 battery packs that basically cost $10. Total garbage
