The drawers have always been a nightmare in our freezer. The flange (I think that's the word, the splayed out bit) on the bottom of the drawer isn't wide enough to sit on the inbuilt plastic runners and so slip off of it isn't exactly straight as you push it in. Over time, a dink has developed making it worse and worse.
I was woken by my phone at 2.30am by my dd who, in trying to get some bread out of the freezer, got the drawer completely stuck and couldn't sort it out. It took me a good while to get it back in and as a result took me far too long to get back to sleep. My sleep isn't great at the best of times, currently not helped by out by my dog who is up between 4.30-6am needing the loo (an age thing), so this wasn't great. I'm always happy to help her btw. She is disabled and her sleep patterns are very much governed by her chronic pain condition. But she could have really hurt herself trying to sort this out for herself.
Below the drawer there is a plastic covered metal shelf which I think I could use boxes and smaller storage containers, I just wondered if anyone else has done this and what you used. And if there were any issues and you had to go back to using a drawer.
