I really wanted to like these. They are great to reduce the amount of rubbish and save a little bit of money. The quality is also good for the price.
However, they are slightly smaller than a regular Australian size baking tray, my trays are all the same size but different brands and there is a bit it doesn't cover on each side. Although, this is partially my fault because i should have checked the dimensions.
The biggest issue that I have is that they are horrible to clean. It doesn't matter the amount of time and effort I spend cleaning these after I use them, there is also a film of oil left on it. I end up cleaning it, letting it dry and then cleaning it again which does the job. Putting it in the dishwasher doesn't make a difference. I'm not sure i would purchase these again.
