We use the Bomann-hood to calm our daughter .... Our little always needs to calm noise. So we have in different forums of hair dryer, CD, cooker hoods, ect. Read. The Bomann hood is very power-saving (compared, for example, with a hair dryer). Now this is already for 4 months enben our baby bed and runs every night until our mouse smashed. Optimal is the integrated light which shall serve as a night light. Can only recommend for all stress-afflicted parents the device!
