b.box Sippy Cup with Weighted Straw vs ezpz Mini Cup + Straw Training System
Which should you buy? Our verdict on both, pulled from our full The Best Sippy Cups: 4 Compared (and One to Skip) comparison.
The b.box is the one cup that covers every situation: it drinks at any angle, it genuinely stays shut in a bag, and cheap replacement straws keep it alive through years of chewing. The ezpz is the better teaching tool and the easiest to keep clean, so many households end up using both.
b.box Sippy Cup with Weighted Straw
Buy itThe weighted straw drinks at any angle and the seal actually survives a diaper bag, which is why it outlasts most first cups.
- Weighted silicone straw follows the liquid, so it drinks reclined, tipped, or nearly empty
- Two-way valve holds up through bag tosses and high-chair drops better than typical flip-top straw cups
- Fully disassembles for the dishwasher, and replacement straws are cheap and easy to find
- Flared base resists tipping and the soft handles suit small hands from around nine months
- Fast flow can startle a baby under one until they learn to pace sips
- Sealed cold then warmed, it can squirt on the first press, so vent it before handing it over
- Chewers will eventually flatten the straw tip and need a replacement
ezpz Mini Cup + Straw Training System
Buy itA weighted silicone open cup with a short straw lid, and the easiest cup on this list to keep genuinely clean.
- Works as an open cup or a short-straw cup, matching what feeding specialists usually recommend
- No valve and a short see-through straw means nothing hides, so mold worry largely disappears
- One-piece silicone body with a weighted base is hard for a small child to knock over
- Dishwasher safe and the straw scrubs clean with a small brush
- Small capacity makes it a mealtime cup rather than an all-day water bottle
- Not leak proof: the lid contains splashes but a cup on its side in a bag will seep
- Some children need a week of coaching before the soft short straw clicks
