Hi all,
I have tried so many sippy cups since my first son was born. Now with my second son I'm still looking for the perfect sippy cup. So far the best one has been the Avent sippy cup, as it doesn't pop open if it's dropped on the floor, and it is easy to drink from (some of them are like trying to suck a drink through a pin hole). The only problems are that it does leak into my bag a bit, making spare sets of cloths and nappies damp, and one of them often just leaks everywhere at the point where the lid screws on.

A friend showed me her great Mess-less sipper valves that you can put on top of pop-top juice (and spring water) bottles for toddlers to stop spills. It turns out that the website has sippy cups too. So..... has anyone tried the Mess-less sippy cup? This cup does look ideal, but I'd love to hear some feedback re. the cup before spending more money.
