I have used the Kiddopotamus Tiny Diner Portable Placemats with kids that I babysit and have found them to be very handy when taking them out to eat. I love that these mats are strong and easy to wipe or rinse off, and I love the little trough that catches food. I think the size is great as well - it provides a large area for kids to spread out their food and allows for some small spills, too. I do find that sometimes the suction cups don't stay stuck to the table very firmly and need to be pushed back down often. Also, when you roll up the mats, I wish they would bounce back to being flat again more easily instead of staying quite curled (maybe I should just be more diligent about storing them flat when they're not in use). And I agree that red sauces and other highly-colored food items can stain these mats easily. Other than these things, I really like this product and would recommend it to anyone with little kids.
