Great idea and nice to use on a hot day, though if in a hot space the air blowing will be hot, too. On lower speeds, it isn't very loud, but go up on 4th and 5th speed and it is loud and noisy. Useful item in the heat. Easy to set up and use. Highly recommend.

Even at the highest level I don’t find this strong enough or helpful on a hot day. Used it on a 88 degree day in NYC. Doesn’t help much. The only time I find it helpful is if youre in a space that isn’t too hot and or has some AC such as a train or in doors. I love the concept but needs to bee stronger. Btw your hair will occasionally get stuck in the fan. Not frequently and not terribly but it will.

It charged quickly and is easy to use. Even on low it puts out a good amount of air. As other reviewers state, obviously when you are outside and in the heat it will just blow hot air at you, but that's better than no air circulating around my face at all. I wish the power button was not so easily activated, if you have it in a bag or something it may turn on with gentle pressure by being bumped into by other items. That's why I only gave it 4 stars. I wish that it instead had a slider.

I do some volunteer work outside year round. So in the summer when it's 95 and humid out, it gets more than a little sticky. This fan can definitely help keep air circulating. It's very quiet - even on the highest setting with the fans right by my ears, I can still hold a conversation. It keeps a charge very well, so I don't need to plug it in often. My only complaint is that it's pretty big and a little heavy. It looks like I'm wearing a huge paid of headphones around my neck. If it were a smaller profile, it would be perfect!
