The fan must first be placed on the base and secured with screws. This is self-explanatory and is therefore not a minus. I bought this fan for my office where you just want a little more design. The fan blows hard enough for an office space of approximately 20m2. I have placed it on my desk 1 meter away and then the softest setting is also hard + quieter. (Even quieter than the Solis Tower Fan 749 I also bought). Like other users, I also noticed that even if you just have it on you can hear the sound of the timer. However, this stops after a while, probably due to the winding system. So if you put it on the timer (120 min), and then turn it ON after 5 minutes, it will make the ticking sound for another 115 minutes. For those who use it in the bedroom, the ticking sound can be disturbing, then the Solis Tower Fan 749 is more suitable, for example, which does not have this. Someone else also wondered in a review what the function of the 0 position was since you have an off position, I use this as an off function so that you don't accidentally put it on the timer. The base of the fan is not very solid, so it is not very sturdy and occasionally wobbles when it is placed on an uneven floor. However, the fan will never tip over. In short, a great fan for a good price and with a nice design.
