Cool Gadget For Babies And Adults

My sil recently got a cool gadget for the gals from Hong Kong, but mummy and daddy can also use it. It’s a anti-mosquito device, specially designed for babies. The device operates by emitting ultrasounds within a range of 3 metres which annoy mosquitoes without causing any undesired effect to people or animals. It operates on batteries with an average useful life of approximately 100 hours. This gadget is so small that you can fasten it to your clothes, babies’ strollers, planpen, just on anything. Cool or not?
