For a smaller outdoor area or balcony with a surface area of 30 square meters, it is not suitable. It is very powerful and noisy even at low speed. Ideally, calculate it for a surface area of 30-60 square meters. The construction of the central mechanism seems sturdy and compact, but the protective casing is completely flimsy and easily gets damaged. For 50-60 euros, it is definitely a fair price, although the noise can be tiring.
