Dyson’s handheld fan is more powerful and louder than I expected

Dyson's new handheld fan, the HushJet Mini Cool, is powerful but loud. It's slim and sleek, with a rechargeable battery and spinning blades contained in a compact body. The fan is easy to use, with a toggle switch and rocker button for speed control. However, it's not ideal for quiet use and the battery life is limited at high speeds. Engineers may want to consider this product for its compact design and performance, but be aware of its limitations.
