The worst thing I have bought. The air it produces is equivalent to that of a mosquito. The motor makes noise as if the propeller is touching the cover internally. When you put it on the warm air option, it is simply useless. It consumes 7 amperes unnecessarily. Besides that, it is also dangerous for the car because it does not have a fuse in its power supply, and the connecting cable is not suitable for its power consumption category. In ten minutes of operation with almost nonexistent lukewarm air, it started to smell burnt. I simply wasted my money
