Dear Jisulife my roller speed doesnt work what should i do?

Make sure you press down on the wheel to turn it on after turning the rear switch on. Then the jog wheel should work. If that doesn't help. You need to return it for a replacement.

Is the cooling effect of this fan really good?

Yes. It works good for a personal fan. Add in a cooling towel on your head and this thing is like having A/C outside.

Dear customers: The size of this portable mini fan is only 6.14*2.38*2.28 inch 0.47lb, you can put it in your pocket or bag, and it is also equipped with an anti-lost lanyard, so no matter where you go, this handheld fan can keep you cooling, it is your cooling companion for traveling and outdoor sports. Sincerely, Jisulife

I purchased the warranty along with this fan. I can’t seem to find the warranty info in my email. Can you resend it pls

I never gotten mine in the delivery. It was lost. I contacted amazon many times to help me but j stead if helping me, they turn their back away and refused. So sad experience. Very inhumane..not good…
