nubite helps with a fast and efficient relief for itching, pain and swelling caused by insect bites and stings. Our device is 100% natural and completely chemical-free – the technology uses concentrated heat to neutralize the enzymes that cause itching and burning. By applying the device 10-12 seconds to the bite or itching area, the concentrated heat eliminates the itch-causing proteins injected in your skin. This is a great way to stop the itch by not using any dangerous chemicals or anti-itch creams. It works easily for mosquito. flea, bees, ants, wasp and other insect bites. Compared to similar devices, nubite does not require any external batteries and the built-in lithium battery with a hidden USB port can be used for up to 300 applications.
