Good is that the battery does not last even 1 hour, but I bought another battery with a larger capacity and only 2.50€ and it lasts much longer!

The problem with this device is the slight vibration that you feel in the spine, it gives good air though, and the fans you can easily take them wherever you want.

To me, on the small/first scale it lasted about 40'-50'. For the minimal amount of money I paid for it, I find it VERY GOOD. It helped me for a little while to catch my breath, but the description mentioned a much longer battery life.

Low quality and noisy, yet effective. The battery life, in relation to the charging time, requires you to have two in order to last the day. If there was a better competitive product, then I would give it 3 stars instead of 4.

Very plasticky - the charging port it has does not have the plastic properly cut around it, so it does not fit easily. And it makes a lot of noise, a buzzing sound like that of a drone, with a very gentle breeze.

It's fine. Just what you need for the summer months at home. Not a lot of air, but enough to keep you from melting in the heat.

I have it for 3 days and I am impressed. It can be worn around the neck or if you want you can have it at the office. Very powerful cool air, even when walking on the street with heatwave. Especially now with covid, for anyone wearing a double mask and experiencing heatwave, it is an oasis of coolness, VFM!!!!!!!!!!!
