Everything is fine

I bought two of them and they do their job very well. The dual power supply is very convenient.

These fans are actually quite powerful for there size and are useful

I have to try it, but it’s a really good idea.

This little fan is so heavy that it pulls down the brim of the hat and covers the eyes.

Kept looking for the hat until I saw the advert again..
Not very powerful.

It works, but it’s not practical. I don’t recommend it.

cool cooler but its only useful while working from battery, working with sun battery provides very low rpm under cloudless sky full of sun. the question is if the sun battery actually charges the cooler’s battery, if yes – the thing can be useful, if no – its useles) its own battery goes off after 1 hour :d

Thank you and good luck

I didnt read the description and thought it was the hat with fans. Was only the two fans. The fans are good quality.

It works. thanks. don’t have to worry about the heat.

The fans work and perform their function… but be prepared for it to be without a cover! Maybe I didn’t understand the photo correctly.

overall tops. heres the but.. too heavy for some hats and too big for small hats. need a large hat.

I’m very happy with them and I recommend that people buy them.

They’re good!

It’s fantastic!!! Works perfectly!!!! You can charge it and it works, or you can use the solar panel on a sunny day – it works both ways!
