Our standard drawer slides are bent because one of our lovely children used the cutlery drawer to jump higher. Both sides collapsed at the same time. We decided to replace them with something stronger. They are definitely stronger, but it took a lot of modifications to make them work. They are wider than the standard drawer slides so we had to mount them to the cabinet wall instead of the frame, which required a block behind the drawer slides and a cut out in the frame to accommodate the wider slide. It works and hopefully justifies all the extra work.
