### ⭐⭐⭐⭐⭐ Such a quiet fan!!
*by C***1 on 28 March 2017*

I bought this fan to go adjacent and to my hob in my kitchen (which is where this fan is to go in a kitchen). It's so quiet you don't know it's on!! It has two speeds but so far I haven't used speed two. The cover clips off for easy cleaning too.
