As someone who has chronically cold feet, I found immense relief with a foot spa. I had originally bought this cloth foot warmer as a gift, but the other person didn't need it so I took it back. I decided to try it out before I returned it. And I'm so glad the other person didn't want it because I would not have discovered what I was missing. This foot warmer is so much better than a spa because you don't need to mess about with water and the pains of cleaning it, maintaining the temperature, etc. And I find the relief I get from this to be more than adequate. I ended up donating the foot spa because I can't see any reason for me to keep it after discovering this superior foot warming method. I have been using this every day at work and at home whenever I'm on my computer or sitting down. This is way more often than I used the foot spa, mainly due to convenience. It's also nice that it has a built in timer. It's long enough that I don't get annoyed with it shutting off. I think it's at least a few hours. But it gives me peace of mind that it won't stay on forever if I forget to turn it off. I know a few complained about it only being heated on one side. While this is true and it's only heated on the bottom, it only takes a few minutes for the heat to circulate and make your entire foot feel warm. I never had an issue where my feet still felt cold after using it for a few minutes. If you want to improve the effect, just make sure you pull out the fluffy thing over your ankle and it will retain the heat better. In the photo above you can see where I have one side with the fluff pulled out. Make sure you do this because it's easy for the flap to get tucked in and reduce the insulation of the heat I also saw that some complained about the amount of heat. I love extreme heat and take piping hot baths. And I found the hottest setting to be more than adequate. It heated my foot to a point where it might be too hot if the temp were raised just a little bit. I took some readings with my temp checker in the photos. The hottest setting temp is around 103F and the coldest around 91. Note the temp jumped around a bit and was a little hotter or cooler in places but that's about the average. I did find the coolest setting to be colder than I liked. But still better than nothing. But the warmest setting was great. One other benefit is I believe using this daily has improved my circulation to a point where I am seeing other benefits. I normally get migraines every few weeks, but I haven't had one since I started using this. I'm not sure if it's a coincidence or not. But I've also noticed that my chronic dry skin issue on my feet and to a lesser extent, hands, also improved once I started using this. My uninformed speculation is that this might improve circulation in the whole body by expanding your veins/arteries in your feet. It would make some sense to be because I feel overall a fuzzy comfortable feeling when I just this. The only negative I found is that the material on the inside does become depressed over time, loses its fluffiness, and little pieces of dirt will get stuck and matted in the fibers. I've included a close-up photo of this after using it for a few months. It still works fine though and I don't find it to be that big of a deal. I found the cord length to be great too. Yes it's long, but the length lets you extend it from far off plugs. I find the placement of the device to turn it on good for hitting it with my foot to turn it on. However one downside is the back of the switch device is not flat. So it easily can get turned upside down if the cord gets twisted the wrong way. Overall, I am extremely pleased with this product. I will probably use this every day for the rest of my life because I don't ever want to go back to having cold feet.
