Query: Very Disappointing

I have had this for 6 months now, and have generally not been impressed for the following reasons:1. I'm not sure why, but the sides of the top container have split, ( Yes, the metal has actually split ), so liquids will leek out. I think this is because the clips are so tight2. The clips are really tight on the top lid, and the lid jams on and is really difficult to get off ( have to twist and pull a lot ). This is the same as the other 2 star review here mentioned3. Because it is made of metal, if you put anything hot in it, the Tiffin gets really hot, and the food will cool down quickly, so if you want to put hot food in it, I would not recommend itI use mine every day to get food from the work cafeteria, so it gets a lot of use. But because of the splitting I have had to throw it away, and get something else
