This a pretty cool, unique design that allows kids to drink from any angle, 360 degrees around the cup's edge just like a real cup. It is also really leak proof, thanks to a cool inner silicone seal that rests between the lid and the inside of the cup. This cup scored 75 out of 100, losing points primarily in the eco-health department, and for ease of cleaning. While the cup failed to meet the eco-health metric score we like to see, it was easy to use and easy to clean, which made it a cup we sort of liked, and would recommend for a more cup like experience than the spout type sippys.
Sassy Grow Up Cup Review
Pros: Unique design, 360 drinking options, easy to drink from
Cons: Low eco-health score, hard to clean inner leak-proof seal
Our Analysis and Test Results
The Sassy Grow Up Cup is a unique BPA-free plastic cup that has no spout of mouthpiece. Kids can drink from any edge of the cup just like an ordinary cup which helps them learn the proper muscle memory for future cup use. The cup is lightweight, easy to clean, and dishwasher top rack safe. It has a inner lid seal that prevents leaks for 360 degrees. The cups come in various colors and styles and are widely available in stores and online.
The possibility for injury is also smaller with this cup. Given that there is no spout, or hard plastic protrusions on this cup, it might mean there is less chance of lacerations, or facial injuries if a child were to fall while using or holding the cup. Certainly no more potential for injury than a regular drinking cup might have.
This cup was surprisingly easy to use, once you understood the underlying concept. If the user attempted to adjust the cup lid before really giving it a good sip, they might have found themselves wet, but when used correctly with a secure lid this cup was easy to drink from, easy to maneuver with the ability to drink from all sides, and easy to hold with the tapered cup design. This cup earned a perfect 10 for ease of sucking; a key metric in whether of not a sippy will be used.
This cup did not score well for eco-health, or for ease of cleaning. The cup is made of plastic, which we feel is the least healthy option available when it
This cup was harder to clean than some of the other cups in our test. Primarily the inner seal, or leak proof component of the cup, was somewhat difficult to get on and off, but worse still it was hard to get truly clean given the tiny groove nature of the gasket. The seal has very narrow, groove-like channels, that zig zag from one end of the seal to the other. It is this mechanism that makes the cup leak-proof (plus it looks kind of cool). However, this is also what makes this cup harder to clean. If the cup only contains water, then it isn't such a big deal, but if it has dried milk or similar in the cup, then these grooves become a real bear to tackle. Soaking and massaging are necessary, but its the time and effort that makes it a real problem, and it takes significantly longer to clean properly than most of the other cups we tested.
