I have some badly fitting down lights in my kitchen ceiling and have been looking for a solution of how best to fix the holes the down lights fit into as the plaster board is all cracked and they don't fit properly and look terrible. After searching for months for a solution I have found this great new product from C-FIX. They not only have a product to repair the hole, but also a metal liner as well. Very easy to fit and now I have perfectly fitting down lights! The C-FIX website has plenty of how to video's and info about fitting both the repair kits and liners https://c-fix-downlighter.com
