Our Verdict
The NUK Lerner Cup is an interesting leak-free cup with handles for little ones to grasp. The parts are easy to assemble and clean, and the soft spout helps prevent injuries related to hard spout sippys. Unfortunately, many testers found the spout challenging to drink from, which may make it a better choice for breastfed babies who are used to a more powerful sucking process. Although this difficult valve could be the reason it performed so well in our tests for leaks with a perfect score and not a drop missing during testing. The NUK is also plastic which isn't our favorite given the potential for plastic to leach chemicals into their contents. However, the reasonable price point and soft spout could make it a good match for parents who need an on-the-go option that is inexpensive and leak-free.

This straightforward sippy is a good transition cup that little testers seem to like.

This cup is leak-proof in both the upside down and sideways leak tests making it a good option for on-the-go adventures. Being leak-proof is a primary concern for this type of cup, so this is a big plus. We like the smaller size, shape, and nubbly grips the NUK sports that make it easy for even the youngest sippers to hold and use.
The Nuk Learner Cup is easy to clean and assemble and can be used without the handles if you need to fit it in a cup holder.

This cup is also easy to clean, take apart, and assemble and it doesn't require special tools to clean beyond the standard bottle brush. The NUK's spout/valve could be cleaned with a straw brush but it isn't 100% necessary. The silicone spout is soft and nicely shaped. We like that it is silicone, not plastic and that the shape is nicer for transitioning.
The valve on the NUK prevents leaks but it is so powerful it can also be difficult to get liquid out of when drinking.

Dislikes
The NUK's spout/valve is harder to use than most of the competition. Even adults could barely get the liquid to come out. For a transition cup intended for babies, this seems counter-intuitive, but for breastfed babies who regularly use more sucking action than bottle-fed babies, it could be no big deal. However, the valve difficulty means it does not meet the American Dental Associations “no valve” preference. Given that the main concern about valves is the amount of sucking a child needs to do, we feel that the excessive sucking required for this sippy is further from the ADA ideal than we would like.
The NUK is plastic which is not our favorite choice for babies or the environment.

This cup is BPA-free plastic which is not an inert material like stainless steel. However, being BPA-free does not necessarily translate to being 100% healthy.

Conclusion
There are lots of things to like about this cup, including the thoughtful handle design, silicone spout, leak-proof valve, and easy cleaning. On the flip side the cup is difficult to drink from and it is plastic. However, if the plastic doesn't worry you and you avoid letting any liquid sit in the cup for long periods, you may find the lower price and tough valve operation meet your on-the-go needs with style.
Worried about this valve?
Purchasing this cup through a retailer like Amazon means you can test it for yourself and return it if it is too hard to drink from. Save the packaging and test your cup right away to avoid return hassles.
