If your not good at arts and crafts don’t buy this!!

If your not good at arts and crafts don’t buy this!!
So, the looks of the pictures on line..... I thought you would have to just hook the cord up, and place the insole in your boot. Not have to play arts and crafts. Make slits, and run cords through and do a whole type of “build it yourself!!” Type of thing. This is really confusing. Also I want heat all over my foot, it seems like the green circle is where you get the heat from in the picture strapped to a cord. (I don’t think the cord heats up at all. But have not tested it yet)I didn’t play arts and crafts yet. I usually get the full sole 9 hour feet warmers that you have to keep on replacing every time you use them. They work great but I did the math and how much I ski all the time if I bought this I would be saving money. So just to let you know it’s not easy to install that’s why for the money I gave 2 stars bc if you don’t know what your doing then your all done. Which is me. If I find someone to help me with this and they work great I’ll get back to you.I did however give you pictures of how to install it. So that way you know what you are getting into and that way you could save yourself and the company some time and money.It already comes with clips so you don’t need to buy extra. Also it come with USA and EUROPE 2 prong for charging.Also package was ripped and damaged when I got it. The Amazon box was fine but the package itself was ripped and it wasn’t bc of delivery. So maybe someone else got this and tried to open it and ripped the box. Then they saw what they had to do and send it back and then Amazon sent it to me... 🤷‍♀️EVERYTHING IS IN THE PICTURES
