[This review was collected as part of a promotion.] I will never buy another cup after this purchase! My son would agree that no other cup holds a chance compared to the durability and quality of Zaks brand. We highly encourage your products Zakaria. Thank you for your commitment to service.

[This review was collected as part of a promotion.] These cups are the best. My kids are hard on their cups and these can take a beating. As a busy mom, I especially love how easy they are to clean--the straw part easily pops out and can be soaked in a bowl of hot, soapy water and the stainless cups I can pop in the dishwasher. No leaks so far! We plan to buy more!

[This review was collected as part of a promotion.] I love these stainless steel cups. The Disney Princess prints that we have are so cute. The stainless steel keeps the drink cold longer than your typical plastic cup. The straw comes apart so it’s easy to keep clean. So far there haven’t been any spills either!

[This review was collected as part of a promotion.] Our 8-year-old loves Spiderman, and we thought these cups would be a hit and a good replacement for the old "sippy cups". As it turns out, they were even better than expected. The cups are well made and leak-proof, with bright colors and fun designs. They are also very easy to clean, with wide openings and easily removable parts. The unexpected bonus was that these cups also work very well for my 89-year-old father-in-law. Unfortunately, he is bed-ridden and has a difficult time using a regular cup due to arm tremors. These cups work perfectly for him, allowing him to sip easily and not spill a drop. They also seem to keep drinks cooler for longer than other cups. All-in-all, a win for all generations!

[This review was collected as part of a promotion.] These are nice stainless steel cups that come with a straw that are great for traveling with kids. My grandson likes star wars so I picked up that one which comes in a set of two. These cups are 12 ounces which is perfect for kids and since they are stainless steel they actually keeps the drink cold. Very satisfied with these so if you have kids give them a try.

[This review was collected as part of a promotion.] Great cup only one flaw because of the straw it will leak if upside down. My daughter loves the designs and I love the sturdiness of the cup. Thankfully my daughter is at an age she doesnr spill often or turn her cup upside down. Overall very nice cups.

I bought these from Sam's after using other zak water bottles just like the purchased from other stores. These were bottles are completely faulty and leak from the lid even when it is completely screwed on. Terrible waste of money and it damaged my wood floors where it leaked.

I bought 2 packs of these right before Christmas for my Grandkids It is now just Feb and my daughter said that the pieces inside the top of the straw are deteriorating and have almost completely came out so they are leaking.I paid 16.98 for these and they should have lasted much longer than this.But in checking the website it says warranty does not include the straw which is crazy it is part of the cup.Very unhappy Grandmother

[This review was collected as part of a promotion.] I got these tumblers to try. I wanted to see how effective the straws were in staying clean. I cleaned them with each use. The straws never built up any residue in the straws. The lids stayed clean around the rim. Even when they got tipped over, it rarely spilled over. Overall, it was a time saver with cleaning it and cleaning after my little one.

[This review was collected as part of a promotion.] I got these cute cups because they had Yoda on them with a straw. My 6 year old grandson always wanted to take his drink with him in the bedroom so he could play his games. I dreaded hearing "can I have a paper towel " because I knew that meant he had spilled something. Since I got these two tumblers I don't have to worry about the spills, or leaks, and keeping the 12 Oz. cold or hot. We are both happy !
