I still don’t know if it catches a bug as there’s not too many flying critters around at the moment but it looks really cute despite of being a wee bit loud when working. The delivery time was brilliant, like 10 days to the east of England so, happy to recommend both product and seller.
I haven't tried it yet, but it's the same as the description. It has an ultraviolet light that attracts mosquitoes and a fan that sucks it so they don't escape. It has nothing chemical, it seems the effectiveness is that the mosquito is dehydrated after a few hours inside the device.
