Totally useless device which fails after a short period
on 3 September 2010
I bought this product to help me judge UV levels on a holiday on Crete: the island can have hazy days, and there is usually a breeze, which when coupled together can disguise how strong the sun can be, even late in the afternoon. And with two small children, I wanted to be sure that I wasn't being too careless with the sun protection.
However, the biggest drawback with the product is that it doesn't work. After a few hours of exposure to Cretan sun, it simply stopped changing colour altogether, and stayed white. I hadn't left it in the sun for hours or got it too hot, but it simply just stopped changing colour around 48 hours into the holiday. Which meant it became totally useless, and worse still, it stayed white, suggesting the sun was safer than it was.
I can't recommend this product at all. I am giving it one star as for one short period it did work.
