This is a really good product. It does exactly what it's supposed to do. We've used it in our new downstairs bathroom and it produces absolute privacy. It's a bit tricky to cut and then apply so that there are no air bubbles and actually easier to do at night with the lights on rather than during the day when back-lit from outside. However this is not a criticism of the product; I'm not sure how it could be improved. Really pleased with the results and it a actually looks like frosted glass... got enough left to do a small window in my shed
