I was instantly impressed when these arrived, compared to the standard run of the mill ice cube trays that I think everyone has these were a lot bigger. They are the same length as any standard tray but these have a slight wiggle to them and are about twice the depth, and having the lid means once I had filled them with my filtered water I could put the lid on and then carry them to the freezer without the usual slopping of water spilling out.
Once the water has frozen the cubes are so easy to get out, with them being made of flexible food grade silicone and being larger you don't need so many in your juice.
