No faults with this at all. I use it for various foods, including pasta, rice, sandwiches, salads and yoghurt with fruit and it is consistently good. You do need to ensure the lid is adequately fixed, but that is common sense. Watertight and functional, as well as environmentally friendly as you don't throw anything away. I can't remember if this was suitable for dishwashers, however we always wash plastic by hand to prevent warping, so can't comment on that. I often get compliments about how kitsch this is, and it is still in the same condition as when I bought it, so longevity is definitely a positive point.
