Maybe I am the only one giving a bad review!!! This particular fan is small and weak. It does not produce enough air at all for when you are at the table or at a desk. You feel unbearable heat and no coolness at all. Also, the fan head is very sensitive. If it falls from a great height and many times, it will definitely break into pieces. Additionally, you need to watch out for vibrations (if the fan tends to vibrate constantly, it literally "leans" and falls to the floor). I do not recommend it at all. I don't even use it. I was given it as a gift from a mini market. Personally, I would never get one with an adjustable head...

Positive: Satisfactory air flow, relatively quiet fan.

Negative: When it operates, the entire device vibrates, causing the vibration to pass to the point where you have it placed. For example, I placed it on my desk to cool a hard drive that is plugged into a dock, and I had to place cushions underneath it. And even so, the vibration was reduced to some extent, but not 100%.
