Safe Sippy 2 by Kid Basix

1. Slate.com

Author Chip Brantley assembles a panel of 22 parents to test about a dozen sippy cups for ease of use, ease of care, style and leakproof-ness. Parents rate each cup using a numeric ratings system for each criterion. The Safe Sippy 2 is first-runner up with a total of 46 points, out of a possible 50. Parents like the appearance of the Safe Sippy and its ability to keep beverages cool. The main downside noted is the inability to see how much liquid remains in the cup.

The Safe Sippy 2 is given a high confidence rating (meaning editors deem it safe), and although the Safe Sippy 2 isn't given an overall rating, the original Safe Sippy earns 2 stars out of 5. Editors say the angled spout is awkward to drink from.

This brief review doesn't address leaking or ease of use, instead focusing on the overall features of the Safe Sippy 2, such as the silicone sleeve for temperature control and ability to convert to a straw cup.

The Safe Sippy 2 has an average rating of 3.5 stars out of 5 in more than 55 owner-written reviews. Parents report few issues with leaking, and those that experience leaks tend to have the problem only with the straw attachment. Parents suggest that the Safe Sippy 2 is better for older toddlers, because the straw-like spout is confusing for babies.

Just over a dozen parents contribute to an average rating of 3.5 stars out of 5. One parent says moisture can collect between the silicone sleeve and the stainless-steel body of the cup, which leads to mildew over time. Most, however, say the Safe Sippy 2 is easy to clean and looks stylish, and many appreciate the ability to transition from the spout to a straw as a child develops.

NatureMoms.com covers about a dozen sippy cups in two reviews, assigning each cup a child and parent rating. The original Safe Sippy is included in this roundup, so the straw adaptor isn't addressed. The author points out that the silicone sleeve doesn't get as cold as the stainless steel cup, so a child's hands won't get cold while holding the cup.
