Highly recomend
These are the best toddler cups I’ve found. No leaking, but still easy enough for a young toddler to sip. After a year or so I did replace the straw pieces due to issues with leaking but the Zak website provides a cheap straw replacement for this. Overall, I love these cups and recommend them to all parents.

My favorite cups for my 2 year old. Just be careful if your kiddo drops it! It will hurt your foot and dent your floor. It does dent easily if dropped outside. But it doesn’t drip the same way other cups do

Won't buy again
Designs come off easily after just a few runs in the dishwasher. Toddler cant suck his drinks out of it as easily as other tumblers like the Reuse ones.

Good quality cup!
Cute cup for a little boy! Seems like it is good quality. It keeps drinks cold and doesn’t leak when tipped over. I do wish the internal straw was stainless steel instead of plastic, but overall would recommend!

Print comes off over time
Cute color and leak proof but do not leave it soaking in water in the sink, as the design print has completely come off after about 6 months use.

paint flakes off instantly, health risk
I bought this tumbler on 9/21/25 and I'm writing this review 4 days later. The blue paint on the tumbler is flaking and dissolving off onto every surface I set it down on (see pictures). We've handled the tumbler with care, and have only hand washed it. It leaves blue rings in cup holders and on my child's high chair tray. This product is unsafe for children. The paint could easily get onto my child's hands or food tray and be consumed. This product should be pulled from shelves before a child is poisoned.

Excellent Quality! Cute Design!
Excellent quality! I don’t know why it took me so long to find this cup! This is everything you’d want for a toddler! My almost 2 year old took to it instantly. It seems durable and hoping it will last awhile. Super cute design!

Perfect first straw cup!
Perfect cup for my 12 month old! Seals so he can’t make a mess but doesn’t require him to twist or turn a lid, just drink from the straw! Will buy more designs.

Cute but a lot of parts
Overall I like the cup, but comparing to some similar options there are a lot of parts to keep together. If you have a system for drying and washing it will help, but I’m not sold on all the necessary parts. Print is very cute!

Everything You'd Want
Keeps drink cold for a long time, easy-to-take-apart and easy-to-clean with only 3 pieces, can go in the dishwasher, doesn’t leak when tipped, fits car seat cup holder and liquid easily comes out when drinking. 10/10 in my opinion!

The best!
We’ve tried many cups but by far these are the best in terms of spill proof, ease of cleaning/ taking pieces apart and durability

Favorite cup so far
These are the best toddler cups I’ve tried! Clear straw, soft straw on top, insulated. Check, check, check! It’s easy to clean in the dishwasher and milk doesn’t sneak back up the straw like it does in other cups. It’s mostly leakproof, as in, it won’t leak in your bag, but my toddler can still manage to mess with it and spill a little if he tries hard enough. I will say, the designs rub off over time and I personally don’t like any of the designs. I wish there were solid options.
