Zak Designs 30 fl oz Stainless Steel Straw Tumbler

It seemed to be a well made cup but seems to be a little heavy, my daughter didn’t like it!

Easy to clean. Keeps drink cold for the whole workday!

I bought several of these cups for teenagers in Foster Care! They really loved them

Love it! Keeps things cold for a long time and holds a lot of water. For on $10, this was a great buy. The comments that say it’s too heavy… why did you buy a large tumbler then?! It’s really not heavy or larger than other similar tumblers that hold the same ounces. Picture comparison with a can for reference. Also love the design!

Nice smooth cup but way to heave to only hold 22oz

I wanted a water tumbler that stays at home to get me to drink more water. I didn’t want to spend a lot of money. For 9.99, this is great quality, holds a lot of water, and does the job perfectly.

It’s a great tumbler for the price, easy to clean and very sturdy build. Just wish the color was darker because it’s lighter than the display photo.

Holds ice better than my Stanley. Fits in a cup holder. Heavier than I expected but I think that’s why it works so well.

The best $10 I’ve ever spent. Keeps ice cold all day 8+ hours

Love this cup. A handle would be nice.

It is sooo cute and it helps keep me hydrated ALL DAY!!! it keeps my water cold too

Love the design on the outside and the easily removed lid (screws on/off). The straw hole isn’t sealed, so it will leak if tipped over. I’m not clumsy, though, so not a worry for me! Keeps ice solid for at least 12 hours. I left mine on my beside and came home from work with it still frozen.

This cup is bulky and awkward to hold. It's too wide at the top and can easily be tipped over. It seems to be cheap for the quality but this design makes that not worth it.

I really like that this holds 30oz but didn't feel bulky or oversized in my hand. Fits great in a cup holder. Didn't spill when it got knocked over. But the problem is that it doesn't hold ice very long.

Solid cup. We took it camping this past week in the 90 degree weather and it kept ice and water cold for most of the day. It did have a lot to compete with so I was happy with how long the drinks stayed cold.

I have several water bottles but I need a straw bottle without handle for sipping lemon water to avoid tooth enamel erosion. I previously had a Starbucks cup that I put in the freezer and it broke. I didn’t wanna get another Starbucks cup because I don’t like the company and using their bottle felt like marketing for them for free. So when the Starbucks bottle that was gifted to me broke, I’m like good riddance! I came across this beautiful Zak cup at the isle by happenstance, and it’s the perfect size that I need. The quality, size and price is unfuckingbelievable. This is a great product. It’s not your average cup. It’s slick, unique color waves, well insulated and keeps drinks cold for the longest time. I highly recommend it. The colors are beautiful. I got the sage green. I’m on the hunt for the navy blue color. Thank you to whoever came up with this concept. I’m blown!

This tumbler is such a great alternative at a great price point. The modern design is great and so easy to clean! I put ice water in before heading out in the morning and it’s able to stay cool all day!

Love the design, very calm zen pattern. Esthetically it looks great. Keeps drinks cold. It's really big though so just something to keep in mind. Good chance it'll last you all day. I dont think I've ever needed to refill it during the day.

I loved the color!! And the price !! It would’ve been way better if it was spill proof ! Other than that the color I got is beautiful, I bought a bootie for protection for the bottom of the cup from Amazon as well the straw topper.

Can’t be the price $10.00, after 12 hours on a hot day 🥵 it still had plenty of ice. I was impressed can’t wait to see more colors on the shelf.
