Review on Bebamour Click Lock Weighted Baby Sippy Cups With Removable Handles No Spill Toddler Sippy Cups Transition Cups With With Duck Mouth Cover, Bottle Strap Set (240 ML, Green) by Danierl Temple

Update. Like this cup. NOT LEAK proof. This cup is suitable for 2 years and up. Not suitable for ages 6 to 12 months. Hard to get fluid out. Child has to bite the straw to add pressure to get flow going. Which is hard to do at the same time. Child will get frustrated when hangry. I tried it myself and see how difficult it can be. The straw creates a suction when closed. And fluid comes out and leak everywhere. It's pretty annoying. But, it's a good cup. Need to improve on the defect with the straw.
