Wao interesting helpful and useful find. I totally appriciate your effort. Many peoples doing job on bike. Salesman and students daily using bikes. Without helmet you can not drive bike because it is very dangerous. Sometime whether is rainy and your helmet mirror is totally wet and you can not clearly see the road. Its very dangerous for riders. It is best mini whiper. This whiper very easily clear your helmet mirror. Kindely tell the price of this whiper.? Really very cool hunt. Thanks for sharing.
