I bought a water heating blanket for my mother the year before last, but it stopped working last year. I asked the manufacturer to repair it. I only added a little water, but it still didn’t work. I asked the manufacturer again. The manufacturer Tui shirks responsibility and says that the damage was caused by my failure to take good care of it, and the manufacturer is not responsible. This manufacturer is really bad! I couldn't help it, so I bought a Coslan electric blanket. It was really easy to use. They were testing it when they sold it. You can touch it directly after the wire is broken. It won't shock people. The electric blanket can be heated when placed in water. , also tested electromagnetic radiation. Theirs has no electromagnetic radiation and is much easier to use than water heating blankets. It’s also easy to take care of. I like Coslan.
