What parent testers had to say:
I absolutely love these NaturalFit straw cups and recommend them to any parent that is tired of buying cups that leak or simply do not last for longer than a couple of weeks. My 4 year old and 1 year old loved them right out of the box and have used them daily, whether lounging around in the house or stepping out to run errands and/or enjoy some family fun. The design of these cups makes it easy to slip into a diaper bag without a problem and they are so durable that I have not had an issue with spills or messes. They are also super insulated, which was a huge perk for me being that I live in a very hot state and always have to make sure my kids have cold water with them all of the time. The price is not too shabby either! =)
I did really enjoy this product. It has great features at an affordable price. I like the size of the cup for going out and about with my son. We can fit enough fluid in the cup for several hours away from home. I also really like the insulated part of it as well. It makes it easy for my son to hold on to because it does not sweat and get slippery and it also is able to keep his fluids cold for several hours. I also really love that it does not have a lid that is detachable but still has a way to keep the straw covered. My son loves to throw his cups on the ground right now and having the lid to cover the exposed straw is very helpful. It is also very durable, seeing as my son has tested that. We have several cups that are "spill proof" but when thrown onto the floor, it still makes a mess for me to clean up. With this cup we do not have a problem. I also love that I can fill it up with something cold and set it in the living room for him to just sip on throughout the day and do not have to worry about him making a mess. A few things that I do wish were a little different are the small areas on the top that my son gets food stuck in! It takes some brushes and scrubbing. I also really wish the bottom of the cup was slightly smaller because it does not fit into most cup holders. Even though I would change those two things, it would/will not prevent me from purchasing more of these cups. I have already recommended it to many of my friends! Overall this is a good quality cup and they are even really cute!
Initially, I was really skeptical about the product. Having tried straw children's cups from other leading brands, the pressure always seemed to build up within the cup that would cause the liquid inside to pump itself up the straw and leak everywhere. This was not the case with these cups! I was very pleased. Your child is required to suck a bit harder on the straw, causing the cheeks to dimple, my child caught on fairly quickly, in order to get the liquid out, but no leaks when left opened or closed. The only reason this product is recovering a 4 instead of a 5 is because of the amount of force required to get a quenching gulp, my child lost interest multiple times simply because he wanted something that flowed a bit faster at that moment.
