The first heatwave of the year has just struck the U.K., with temperatures hitting up to 91.4°F for most of the country. And however much I try to cool my house down, opening and closing windows and blinds at different times of day to keep cool air in and hot air out, I’m wilting.So I was pretty excited when Dyson’s first-ever portable handheld fan, the new HushJet Mini Cool, arrived for me to review. I’ve only been testing it for a couple of days, but here are my first impressions before I follow up with my full review.What makes it ‘cool’?

Unsurprisingly, it’s elegantly packaged; you’d expect no less from this premium brand, and it has an attractive design, which is pretty handy since it’s a portable fan that’s meant to be both used and seen.The fan head features a petal-like design with a honeycomb interior, giving it a slightly feminine look.What’s more, it’s available in three colorways: Stone/Blush, Carnelian/Sky and Ink/Cobalt. I’ve got the Stone/Blush version, which to my mind is the prettiest option, but it might not be for everyone.The beauty of the fan is its versatility and 3-in-1 functionality. You can hold it, wear it or place it on a desktop. It’s been sitting beside me while I work, and has its own non-slip stand to keep upright. And besides being small and not taking up desk space, you can change the direction of the airflow by simply twisting the fan section on the top.It’s easy to use
