There's a lot to love about the Pura Kiki stainless steel sippy with an insulated body and silicone sleeve and spout. The Kiki is a durable, quality option with interchangeable spouts (sold separately) that adjust to your child's development stage, offering multiple years of potential use. Also, this sippy is easy to use, easy to drink from, and highly leak-proof.

Unfortunately, the Kiki is somewhat expensive, making it less than ideal for those with tighter budgets. Also, the bottle and spout require special brushes to properly clean, making clean-up significantly more time-consuming. However, despite these minor flaws, we feel the additional price and effort are worth it for the longevity and extensive versatility of this healthy, eco-friendly steel bottle.

The Thermos Foogo (now renamed "Funtainer") is a child-friendly bottle with an easy-to-close lid that opens by pressing a button to reveal a pop-up straw ready for sipping. This bottle's pop-open cap keeps the straw clean (when you use it) and offers leak-proof assistance that isn't possible without the lid. The straw lacks a traditional leak-proof valve (ADA approved), though it does have a valve to prevent a constant liquid flow should the bottle tip. The Foogo has a wide mouth for easy filling and cleaning and a durable, healthy, insulated stainless steel body. This insulated straw sippy comes in various colors and patterns, including popular licensed characters like Batman and Paw Patrol, so your little one can choose their favorite.

The straw for the Foogo requires cleaning with a straw brush, and children with chompers can potentially bite through the straw top if unmonitored while sipping (trust us, it happened). This absent-minded chewing could result in a potential choking hazard for the younger crowd. The insulated bottle is also heavy and could be more challenging to hold for toddlers. However, if you regularly check the straw, we think the extra cleaning step is easy, and most toddlers will be able to hold it with minimal practice. The Funtainer is one of our go-to favorites for older toddlers excited to drink unassisted.

The Klean Kanteen has a stainless steel container with a hard spout and clear plastic cover. Much like the Pura Kiki, there are various interchangeable spouts available for sale, so it can grow with your child's needs for continued years of use past sipping. This bottle is easy to hold, doesn't leach chemicals, and is durable enough to last for years.

The Kanteen is not insulated, so cold drinks "sweat" and get surrounding items wet. In addition, the hard spout could potentially cause injuries if toddlers fall while sipping. Also, the shape of the bottle is challenging to clean, thanks to its narrow neck design (hard-to-reach nooks), so in the long run, this option is best used with water. Despite these concerns, the bottle is healthy steel, the lack of insulation makes it lighter, and the narrow top is more manageable for smaller hands. So, if you don't mind a little condensation and sip while sitting, then the Kanteen makes an excellent sippy for families concerned about materials.

Volume: 9 oz | Body: Plastic

Must clean 2-part valve

The Tommee Tippee Insulated Sipper Tumbler is a plastic cup with a "rim-like" hard spout. It is lightweight but feels durable compared to some other plastic options while still featuring a budget-friendly price. While the spout is not soft or flexible, it is covered with a softer material and has a lower profile, making it more mouth-friendly than hard spouts that stick higher up. Also, this cup has a two-part valve that is easy to drink from and prevents leaks.

The Tumbler is BPA-free plastic that can potentially leach chemicals into contents like many other plastics. The cup has no cover to keep it clean. It has a hard spout that could cause injuries if children fall while using it, and the valve system requires more time to clean. Overall, it is a useful sippy cup that works well with little effort. If you want an insulated, quality sippy that is lightweight and easy on your wallet, the Tumbler is one to consider.

You MUST remove the valve parts and clean them separately to avoid mold or bacteria build-up between the parts. This two-part valve is how the cup is designed and is not a health hazard if you follow the directions.

The NuSpin Kids Zoomi Straw is a different take on a sippy with a silicone straw that locks when you close the lid. This cup is easy to clean and assemble with no nooks for bacteria, and the straw is valve-free, which is better for avoiding dental decay. Valve-free straw cups are also ideal for thicker contents like smoothies or shakes, making this a more versatile choice than much of the competition.

This cup requires a straw brush for cleaning, and there is a concern about plastic coming in contact with liquid as some users remark it gives water a "plastic" taste. Also, it may not be leak-proof, impacting the ability to use it on the go, throwing it into a diaper bag, or situations where a spill would be tough to clean. Users report that liquid can come out of the straw when it is upright, so preventing a mess may be challenging. In addition, the straw is soft enough that little chewers will quickly destroy it if allowed to chew. But, if you use this cup with water to avoid stains, don't mind the plastic body, and you're hoping to help dodge dental decay, then it could be the right choice for your little one.

Sporting a design similar to a regular cup, the Munchkin Miracle 360 Stainless is an easy-to-love sippy that helps children practice drinking without the mess. This innovative sippy allows toddlers to drink from all sides of the cup, thanks to its 360-degree drinking edge and silicone valve system. It requires sucking, making it different than a regular cup, but we think its grown-up feel is noteworthy and attractive to little ones. In addition, we appreciate its insulated, vacuum-sealed stainless steel body, which is easy to clean and keeps liquids cooler than non-insulated contenders. The sippy comes with a lid to keep the edge clean and limit spills. It is also leak-proof, simple to assemble, and one of our favorite options with a reduced risk for injury or dental decay.

The 360 is more expensive than the plastic products, but we prefer stainless steel over plastic and think the extra cost is worth the peace of mind. Also, stainless steel is heavier than plastic, so younger toddlers may not like holding and carrying it. The lid and valve on the 360 can be challenging to clean. Some users report that the top can get stuck and contents spray if you drop the cup, so it isn't as hardy as other steel options or 100% leak-free. Despite these factors, we like this spoutless cup and believe it is an excellent trainer cup that is virtually spill-free.

For a lighter, less expensive, but similar option, take a peek at the Munchkin Miracle 360 Plastic sippy that is similar in design but uses plastic materials for the body.

Why You Should Trust Us


Leading our sippy cup roundup is our founder, Dr. Juliet Spurrier, a board-certified pediatrician and mother of two. Dr. Spurrier uses her education, background, and mommyhood experience when choosing cups for the review. She emphasized health and safety for each product choice and helped develop the testing measures we use to compare the products. The team also includes Wendy Schmitz, Senior Review Editor and mother of 2. Wendy uses her training in the scientific method to systematically conduct leak testing of each cup and create subsequent scoring and ranking. Wendy and Dr. Spurrier created our first sippy review and testing methods in 2014 and have been instrumental in choosing and testing these products ever since. With over 200 combined hours of researching and testing over 40 cups in the past five years, they have unmatched experience with all things sippy.

After multiple sippy cup reviews and over 120 hours of testing, we have unique insight into this gear type. We chose each cup from our research results of over 50 potential contenders. The cups were purchased and tested side-by-side for leaking potential, ease of use, and cleaning, including the number of parts or required brushes. The sippy cups were also given to tiny testers to determine which were the easiest to use, the most appealing, and could stand up to the typical toddler on the go.

Analysis and Test Results


Comparing cups side-by-side is a great way to determine how well each sippy functions compared to the competition.


Value


When it comes to sippy cups, we tend to lean toward long-term value rather than the lowest price. You'll use your sippy cups every day, and even the most expensive cups aren't so expensive as to be out of the question. With that in mind, we feel the Pura Kiki, Thermos Foogo, and the Klean Kanteen are all excellent choices for the value-oriented shopper, despite being a bit more expensive because they will last for years, and deliver more every day. If you are on a tight budget, it is tough to beat the Tommee Tippee, which performs well and sells for less. The NuSpin straw cup is also attractively priced if you are looking for a basic straw sippy on a tight budget.

Leakage


Each cup was compared side-by-side and ranked from 1-10 for leaks. Contenders with no leaks earn a 10, and those that spill similar to a regular cup receive a 1. We use test results from sideways and upside-down positions. We tested cups with lids using the lids in place. Since little ones are unlikely to put the caps back on, most parents have more significant concerns about leaking in a diaper bag, car, or on the go, so we tested with lids on as parents are more likely to use the cover to avoid spills. The majority of products avoid leak messes.


Some of the cups are 100% leak-proof, no matter what we tried to produce leaking, like the Nuk Learner and the MAM Starter Cup. However, it is important to note that these cups were also challenging to use, requiring significantly harder sucking techniques than competitors. You might consider purchasing these from a retailer with a generous return policy in case your little one can't get the cup to work. Breastfed babies may find these options less challenging as they have been using more vigorous sucking techniques than bottle-fed youngsters.

The straw cups are more likely to leak with the Housaavy Stainless Straw Cup with Lid leaking the most with straw in place. However, it still leaks less when it tips over a regular cup, giving parents time to jump into action before the entire contents spill out or create a mess. The Thermos Foogo, on the other hand, hardly leaks even on its side with the lid open, but it leaks significantly upside down with the lid open. This leaking could be fun for little ones who like making messes.

Ease of Use


Ease of use includes how easy it is for parents to assemble and how easy it is for toddlers to use. Fewer parts mean it is easier for parents to assemble with a lower learning curve and fewer parts to lose accidentally. A straightforward design like that of the Klean Kanteen or the Pura Kiki is perfect for parents who don't want to search for excessive parts or struggle with challenging to assemble valves or lids.

The Munchkin Miracle 360 Stainless has a cup-like edge and is easy for little ones to use. While the rim has an included valve, it is still easy to assemble, and we like the idea of no protruding spout that could cause potential injuries to little ones who toddle and fall while drinking. The OXO Transitions Straw, on the other hand, has several parts that make it harder to assemble and clean, but the straw is easy for little ones to drink from, and the dual handles make it easy to hold and carry. Because this cup is lightweight plastic, even the youngest toddlers can tote it.

Ease of Cleaning


Each cup has a different number of components, from lids and bottle bodies to valves and straws. These parts influence how easy the cup is to clean, as you need to disassemble the sippy and handwash the parts, potentially using multiple cleaning brushes. While some cups claim to be top-rack dishwasher safe, we recommend you wash them by hand in warm, soapy water. Hand washing might mean you need to purchase a bottle brush or straw brushes.

The Pura Kiki is one of the easiest to clean with a simple straight body that is stainless steel and simple to scrub with a bottle brush you likely have on hand. This bottle doesn't absorb odors or stains and is quick to clean with no nooks or crannies. The sippy spout is a little more involved but should be easy to clean with a straw brush or the tip of your bottle brush. It has three parts, and they have a straightforward assembly. The Thermos Foogo is somewhat more complicated with four parts and the requirement of a straw brush. This bottle is intuitive to assemble but more complex than the Kiki. The Tommee Tippee Insulated Sipper Tumbler requires disassembly of the valve, and if you don't, mold and bacteria can grow. This design makes the Tumbler more challenging to clean if you don't know that it requires some disassembly.

Lead Testing


We tested the cups in this review for lead inside the container, the outside, and the spout or lid using an at-home test kit. While we read reports about positive lead tests at hidden solder points on some kid's water bottles, all of our lead test results were negative on the cups in our review. All of the products in our review and the areas we tested were negative.
