I have had the fan for 2 years. From the beginning of its use, when I would stop the fan's operation, the motor would generate a considerable amount of heat which would dissipate in the next 15-30 minutes, and there was also a smell coming from the plastic. The fan, starting from this summer, had a low speed which gradually decreased until the rotor eventually stopped rotating. The motor made a noise as if it was trying to move the blade but couldn't. Sometimes, the fan would only start working if I put it on maximum speed. In the end, because the situation was unbearable, I bought another one. The product is faulty, although it has a fairly powerful motor, the quality of the materials is low, and the plastic is not durable, resulting in a reduced lifespan. I would not recommend buying it if you want something that will last for a reasonable period of several years, not just 2-3 years.
