I want to buy an invention patent.

I bought a warm blanket for my mother the year before last, but it didn't work at the end of last year. I asked the manufacturer to repair it, but only added a little water, and it still doesn't work. Then I went to the manufacturer, and the manufacturer tui shirked the responsibility, saying that it was because I didn't keep it well and the manufacturer was not responsible. This factory is really bad! I have no choice. Later, I bought an electric blanket from Koslan, which was really useful. They were testing it when they sold it. After the wire is broken, they can touch it directly without electrocution. This kind of electric blanket can be heated in water, and it has also been tested for electromagnetic radiation. They have no electromagnetic radiation, so they are much better than water blankets. It is also convenient to take care of. I'm Caslan.
