I am really impressed with the fan. The durability is a massive improvement in my last one I bought from the same company and the battery lasts.
I run it off a power bank when it's low and it does an impressive job. I have it to move air around in a cupboard, so far it's more than met my expectations. I highly recommend this, it can be used in a small space, by a bed, a babies pram, at your desk etc the knob you turn is actually positioned on the clamp allowing easy access! Finally forward thinking.
Summer is coming eveeyoev is going to wish they had one of these.
