I just wanted to say how brilliant your screens are for our sash windows. We recently bought two as we live in a second floor flat and have a five month old kitten so were very worried about opening the windows in case she managed to get out. The screens have been absolutely fantastic, especially in this lovely warm weather we've been experiencing. They are light, incredibly simple to use and install and, once in place, you can hardly tell that they were there.

Thank you, thank you, thank you, for coming up with such a simple but effective product.
