Works like it should, keeps my young daughter asleep longer
We bought this after visiting my brother who is a police office and uses a two speed version to drown out daytime noises while he sleeps (he works graveyards) and our daughter (nearly 2 years old) slept the longest she ever has while using his room with it on. We bought this single speed version immediately and it has worked the same. The dual speed is nice if you have it in a small or non-acoustic friendly room as it may be pretty loud even after some adjustments of the vents.
