I have tried so many “leak proof” toddler cups and they have failed me. This brand and cup is AMAZING!!!!! Absolutely no leaks or spill. It’s amazing!! It’s the only cup I let my daughter walk around with because I have confidence her drink won’t spill all over the house. The stainless steel also keeps her drink cold longer which is fabulous for a busy tot. Plus…the design is sooo cute!

This cup is wonderful. It keeps my toddler's drink cold for a long time. I have not had any issues with leaking and it is the easiest straw cup to clean. Going to order a few more of these!

By far the best toddler cup we’ve trialed and there has been so many. Cute, leak proof, affordable. This is it I promise

I absolutely love these Zak cups. We have 3 of them. So easy to take apart and clean. They can leak a little sometimes but for me it's not a huge deal. Feels like good quality and it keeps the ice cold.

Overall this cup is good, easy to use for our 1 year old and leak proof is sufficient. Cleaning is easy enough, but the leak-proof straw requires extra handling/rinsing. I was not impressed that after a week of hand-washing only, there are already a few rust spots on the rim, where the steel is exposed

My son uses it everyday and it keeps his water cold for veryyy long. The paint has started to scratch off but that’s a given with anything and a toddler. Also leak proof!

Cute design and does not leak

My son loves Elmo and we got this as his first big boy straw cup!! It is made of metal and feels good quality, like it can take a toddler beating. It screws on so he can’t just open and spill it, turning it on its side also doesn’t allowing for spilling. The metal feels like it can keep cold drinks cold for long. The only issue is when I tested it to see how easily he can use the straw, I did struggle a bit. I tried to see if I can open the airflow a little but it’s a small silicone hole that can’t be widened so he’s just gotta learn to sip with some force lol. Still very good quality. Very worth it.

Excelente termo, no derrama nada y mantiene frías las bebidas por buen tiempo

Love these straw cups! Nice that it comes in a stainless steel version. Cute designs. Spill proof. Easy to clean

Vino con caja, se agradece

Muy bonito y útil

Amo estos vasos para mis hijos, son muy buenos porque no derraman agua y mantienen el agua fría, lo malo fue mi experiencia de compra ya que tardó un poco más del mes en llegarme el producto, aún recuerdo cuando amazon tenía la promesa de entrega al día siguiente.
