The mat itself is a good commodity. It fits the Model Y RWD and plays a good self-filling role and supports it in a moderate fluffy.
However, the part of the motor to enter the air that you enclosed is too noise, and in less than a minute, it becomes hot as if the fever will burst. You need to divide the crabs and cool them down several times.
The noise seems to be fine if you close the trunk and do it in the car, but... It's a little uncomfortable.
