Nice quality cups. Gave these to my nephews and they love the designs. These cups have a lock switch on them. You open the cup and then pop open the top to drink. That helps keeps the drinking part clean and helps prevents spills.

I finally have a water bottle for my kids that’s doesn’t make a mess. I use it when we fly and when we go to the park. It’s comes in very handy since I don’t have to worry about helping my kids drink from it . They can do it all by them selfs.

The bottles are hello kitty design perfect for girls. Gave them to my sis children who love them so much. It is easy to use and clean. The pack comes with two bottles. This is perfect for those with multiple children. I recommend getting a pair.

Super cute and adorable tumblers. They are perfect for my kids and keeps there water cold all day long. They have a twist cap which keep it air tight. Easy to clean and assemble perfect fit for backpack.

Great Quality and Durable water bottles from Zak. The straw less, snap open spout is easy for my kids to use and drink from. The bottles are sturdy, the right height, and don't tip over easily. I would definitely purchase for all my kids.

I was surprised at how large the bottles were and we’ve always had great luck with Zak products. I love the locking option on the lids and the silicone grip on the bottom of the bottle. Water stays cold and so far no leaks!

I got these water bottles for my kids. They love it. My kids are very picky about their water bottles. It’s hard to find one that they like. These are very easy to clean. And the material is super durable.

Spectacular cups. Nice size, doesn't leak (when top is closed/secured), really solid construction; they're really quite heavy. Kiddo loves 'em, and they seem like they'll keep the drink cool very well throughout the school day.

These are great so far for my elementary kiddo's school water bottle. Good capacity, fantastic insulation! Design work is done well, I think it will stay put for a while through use/washings, unlike most insulated tumblers we've had in the past.

The paint eventually starts to wear off, but long before any of the pieces need to be replaced. The spout and seal are difficult to remove for cleaning. The silicone (?) ring on the bottom, presumably meant to make setting the bottle down less noisy, falls off and gets lost. They do leak if not kept upright or the seals not seated properly. Otherwise, very good, long lasting water bottles that keep cool, however I will be reluctant to buy similar zak bottles again due to the paint looking just awful after long term use. The cups are going strong but look so trashy. Also, the paint does not appear to be covered by the warranty.
