I really like the concept... the lids fit on all my cups no problem and on small mason jars. The problem is with the suction. If you gently press on the top the liquid squirts out of the straw like a fun little volcano of destruction. I will not be using these for travel like originally intended but I will use for picnics and camping happily!

Have enjoyed BOON products in the past, and this one would be great except the suction on the seal is so strong there is a lot of spatter taking the lids on and off. Also sometimes the seal can be hard to control so the pressure when sucking can make it hard for little ones. Great in theory, not perfect in reality :-/
