Really pleased with my new Bi-Folds. I was expecting to have to pay a lot to replace the old ones but the quote was within my budget, I dealt with an advisor from the company and he was clear about the options and didn't push for a sale. They were fitted just in time for the sunny spell so was able to make the most of having them wide open. My favourite thing about them is that when they are open they don't take up much space and slide together to one side.
