This product is exactly as describe - leak proof, reusable, easy to use. Sturdy. I've used it multiple times. However, it's very hard to suck on it if you're using it for a popsicle, which was my original intent. The mouth opening is too big and the zip tie part too hard to put in your mouth. The product in itself is great, but the functionality for my purpose is lacking. Great in the freeze and to use the contents later. Overall a good product. Just not feasible for a popsicle.
