I bought Brush on Block on the recommendation of someone on a running site. I have not been disappointed. It has been used by myself and my wife, we both find it easy to use and does exactly what it says on the box. Although pricey it is lasting well and give the best sun protection I have come across. I used this during the Man v Lakes ultra run 18th June on one of the hottest days of the year and being an ultra run meant I was out in the sun all day, with no sunburn at all. The other advantage is brushing on the minerals means no stinging eyes which I always get with sun creams. I highly recommend this product.
