"I have used many types of handle like this to replace broken ones at the nursery I work for, and all have broken with in 6 months, I put this down to the fact they have all been made of cast metal and have plastic pieces in them. The Eclipse Mortice Handle Pack are made of sold metal and look a lot stronger. The only reason I gave 3 for reliability is because time will only tell. My hope is that the spring will last. Good value for money as well."
