Query: Do not buy this because ---

The hygrometer is not accurate and indicate very high in the beginning.The number came down as it is used to the real value.Considering the price, I thought I should accept this.But it broke two weeks after I bought.So, I returned it and purchased Air-O-Swiss 7135 instead.I only have the AOS 7135 for three days but it is muche better than HWM255.
