A priori, it has a negative opinion under the price. Still, I bought this product I find it very very well for my 50 inch plasma. A little product and a soft cloth shot (included), and this is happiness. All traces leave no trace remains and dust does not come back on. I tried on other screens like laptop, the result is identical. Awesome! Unlike other reviews I've read, the 200ml bottle lasts. It is not necessary to BCP material at each cleaning. A buy without hesitation!
