We just bought a wall fan for the shop. It was not a well known brand and the price is fairly cheap. Unfortunately, after using for 3 days, the fan can't turn from the left to the right vice versa. Well, I kinda expect it. You can't expect much from a cheap and obviously low quality electrical product. But after 3 days, it broke down; I think we paid way too much for the wall fan. Sent it for repair just now though. Let's see how long it can last after this.
