Trainer Sippy Cup

Left marks after first use

This cup is the best I have ever purchased. The design of the handles makes it readily accessible for a toddler and it does not spill when over turned.

We bought a total of 3 of these sippy cups and came across the same problem with all of them. The rubber piece on the inside does not stay in place and causes the entire bottle to leak when on its side or the spout. Constantly cleaning puddles of liquids and refilling the bottle only to have it leak again. Can’t let our son hold the bottle as even when it’s slightly titled the content dribbles out and has soaked many bags and backpacks despite being mostly upright
