"Premium". "Sturdy".
Utter nonsense. This is thin and flimsy like a cheap disposable picnic / ground sheet.

Compact, Powerful, and Long-Lasting Handheld Fan with Extra Features
Color: Pink
I took this little handheld fan to a concert in mid June last year and absolutely loved it. It is small, easy to carry, and holds a charge really well. I have probably used it for over 3 hours on both low and high speeds, and it is still going strong on a single charge.
I also really like that it doubles as a battery charger and a flashlight, which makes it super convenient to have on hand for different situations.
Another great feature is the safety design. The blades automatically stop if anything comes into contact with them, which is appreciated.
Overall, this is a great portable fan that I would definitely recommend, especially for concerts, travel, or hot days outside.

It’s a super good product! Compact but mighty!
Color: Brown
Don’t let the size of this fan fool you! It is powerful, great for a hot summer day, or if your car has no ac, it’s not only a fan it is a flashlight which is very bright, and the topper of all is it’s a phone charger!! For such a small item but packs quite the punch . It is small enough to fit in your purse, pocket or backpack! But don’t let the size fool you!
