My kid can finally have a cup in the car without me panicking at every bump - the tapered shape fits perfectly in our cupholder. The handle is sturdy enough for small hands to grab easily.

Scarlett V. ★★★★☆ Oct 18, 2026

The tapered shape fits perfectly in our car's cup holder, which was the main reason I picked this up. The silicone straw lid keeps spills at bay during soccer practice, though I wish the handle were a bit bigger for my kid's hands.

Claire K. ★★★☆☆ Oct 19, 2026

The silicone straw lid does keep spills contained, which is a plus for car rides, but the straw itself feels a bit flimsy for the price. My kid likes the handle, though I wish it held a bit more liquid.
