Half of it suddenly stopped working after three months of use.

update.
It turns out the controller was the problem. The dealership sent me a new one without much discussion and without any charge (within warranty).

If I could, I would exchange it for another one that has better support legs and doesn't easily slip off the bed.

After a year of use, the cable on one side overheated and started burning at the plug connection with the blanket. Luckily, I was in bed and smelled it, so I unplugged it. After this, I don't trust any electric blanket, thinking about what could have happened if I were in another room.

Very high-quality product. The only negative thing is the lack of a timer, something that personally doesn't bother me, as I set it to "1" and sleep like a baby. I have been suffering from chronic knee and back pain for years, but with this product, I sleep and wake up without any pain. I highly recommend it.
