The bottle part is perfect for a baby, it’s easy grip and the right size for any rugrat that’s looking to hold a bottle on their own. The idea behind the airlock/sippy portion is a good one, but the implementation generally leaves my baby sucking for a long time without getting much liquid.
Cleaning the Munchkin Click Lock Sippy Cup is fairly annoying due to the shape, but not particularly worse than other shaped bottles. I just feel like the bottom of this cup is designed to trap particulates unless you put extremely hot water in, close the lid, and shake vigorously. Your cleaning phobias may vary.
The click lock portion of the bottle doesn’t seem to be anything other than an audible indicator that you’re in the right general area for tightness. Usually when I think click lock I think of something sliding into place to prevent the lock from slipping, this is not the case here, it’s more like using a card in a wheel spoke to make noise.
It could as well have been called a “click unlock” as the thing clicks when you tighten or loosen.
Overall the bottle works, it doesn’t leak, my only complaint is the cleaning and the actual sipping straw portion being too slow for a thirsty baby to get through anything very fast.
Evidently there are also multiple versions of the same named cup out there, so be aware that your friend’s three year old cup may not be the same as something you order today, or tomorrow.
In the end, my baby prefers the Nuby Super Spout Easy Grip bottles, which are the same general concept as the Munchkins, except which a much easier flow straw. Your baby’s mileage may vary.
A two pack of the Munchkin Click Lock Sippy Cup is available from Amazon for $5.88. It’s a good price if your baby likes it.
