You won't realize how OCD you are until your kids have lost each of the bottom rings in less than the first 24 hours… You'll never see them again of you don't superglue them on!! My daughter is the only one with hers left after less than a week, and the three boys' rings have each disappeared consecutively at every place they went. Poor design for kids. I loved them at first, but not anymore just for that.

The bottles seem okay, hard to open, but they are bit durable, and portable. My daughters love them because they look fancy and stylish. Well coated inside and ice lasts for quite some time. Overall decent product. Good enough for kids school time.

My kid loved them! I like how they come in a two pack for both genders. That makes it way easier for me as I have boy and girl. Also they are actually leak proof!! First water bottles I have found that actually mean what they say! Would buy again!

Adorable two pack kids water bottles. I love the stainless steel inside, and easy detach straw for cleaning components. The cap release lock is nice to prevent it from opening when dropped and keep from spilling.

My kids love their new cups. They have a collection of cups but these are far the best. I am able to keep there juice and water cool a lot longer then before. I will be purchase more of these cups for family memebers as well.

Love these beacon bottles from Zak! Each one is 20 oz. Easy to carry since they each have a handle. You can take them where ever you go. Each one have straw as well. My kids love it. They carry them without dropping since they have handle.

These water bottles are so cute and my daughter loves them! The unicorn and butterfly designs are adorable. My daughter loves the ease of the action lid which opens with the push of a button. It keeps her water cold all day and is the perfect size for school. It fits perfectly into the water bottle pocket on her backpack too.

Great patterns to choose from. Holds good amount for children. Kids had no problem drinking from them and when closed seems fully spilled proof. Dino set has hard removable plastic ring on bottom. Elephant set has softer removable ring. Softer one grips almost too much. Wish ring did not remove. Fear is Kids removing and losing. Locking button is confusing. It's hard to tell what way is open. The push button is very difficult for small ones. My 3yrs old can not open by herself. My 6 year old must use both thumbs. Not sure what the purpose is in making it to hard for children to open independently. Over really like these water bottles.

The cups are cute, a perfect size for littles, and keep drinks cool. We must've gotten a defective set again because my daughter had to open the lid to drink out of it. The straw just gave her a headache from how hard it was. Parents tried them, and it was nearly impossible to get a drink. We returned them. This is the second set of Zak cups I have returned for the same reason. Changing brands due to this major factor. We love Zak designs, but this is a dealbreaker.

Keeps the water cold for a long time! It's also the perfect size for my kindergartener's school day. The width of the straw makes it much easier to clean.
