• "They work fine, but they are upside-down compared to most side clips you'd find on anything else. I'm used to pulling up to open, and pushing down to close."

• "I really like the clips. It took me a minute to figure out how to use them, but after the small learning curve it was very easy. I think having them fit so close to the container makes it easy to fit it in a lunchbox."

• "I don't think they can be improved; they are unique and so are a little bit unfamiliar. But, they work VERY well. They get easier the more I use them. They simply go a different direction, latching down rather than upward."

We discussed the clips in depth with our Indian manufacturer and he explained that the reason for the design of the clips this way - attached to the lid rather than the base - is to enable sufficient pressure on the lid to create a strong seal with just two clips. If the clips were attached to the base, there would have to be four clips, one on each side of the base to create enough pressure for the seal to be airtight.  So we have decided to leave them as is.
