In my opinion this gadget is very important for your health and is a great indicator whether UV rays are dangerous. This small wrist band that you wear will indicate if you have been exposed to the suns UV rays for to long.
Scientists also say that sunburn may fade but the damge caused to deeper layers of skin can be harmful and cause cancer. Therefore if you have something which will tell you that you have been exposed for to long then this could prevent health problems in the future.
It has to be noted that it is only an indicator and not a preventer therefore you must use your sun cream with this and preferable a high factored sun cream. I can see this being perfect for your children out playing or if you work outside a lot. You can buy the Sun Protection Clothing Wrist Band UV SunSense now for a good price of $5.87
