The fan is not rotating, but manually rotating (so they are all rotating). False description.

I bought it yesterday.
In the +:
- It is economical (I got it for €7.60)
- It shows good quality construction
- Relatively small (no, it does not fit in a women's bag... unless it's a beach bag type!!!)
- Almost silent
- You can direct the fan towards all sides
- Strong clamp with a good opening (about 4cm) which also serves as a base to stand on a flat surface
- It operates for a long time with 4 AA batteries (so far, continuous 6 hours and still has more...)
- It also works with a USB Mini-B cable
In the -:
- The issue: it has low performance.
- With batteries, it has 6V (4x1.5V), with the USB that it takes 5V, what will happen?
- Not so small (well... it doesn't cover the entire table either!!!)
- Low performance for its size (due to the small blades)
- The clamp is so strong that you can't hold it everywhere, e.g. on the computer screen (I think it will cause damage)
- It requires attention not to let the clamp slip where you hold it
- It did not include the batteries as stated on the website where I bought it ("General information: WITH BATTERY 4*AA")

(There is consideration for a patent in performance. I will come back)
