Zak Designs 30 fl oz Stainless Steel Straw Tumbler

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.

This water bottle is amazing! I have the sage green color which I love. What I like about this bottle is that the bottom is a little smaller so it fits in cup holders well! I also love that the straw has a little ring around the bottom so it doesn’t come out of the cup. It’s super lightweight and easy to carry around!

Nice tumbler! Love the design on this tumbler and the straw. Keep my water cold and keeps ice for most of the day. Good size! While it doesn’t have a handle, it isn’t a deal breaker for me. Love that it fits in my cup holder. Wish it were spill proof though! Overall, it’s a great cup for using at home or the office, just somewhere where you aren’t worried it will spill, hence why I don’t love it in the car since usually coming and going from the car my hands are full. Definitely recommend though!

This is a really great cup that is very well insulated. This cup is very well made and you can definitely tell that this cup will last a very long time. The material this cup is made out of is very thick and sturdy. It is also very durable and it can definitely handle accidental drops. This cup does have some weight to it. I do wish with the weight of this cup it had a handle attached. The best part about this cup is how long it keeps drinks cold. I left ice in this cup overnight and I was amazed that there was still ice in the cup. This is truly the perfect cup for work. I am very impressed with this product and I highly recommend it.

I like the size of this cup. It holds a lot, it's easy to remember to drink enough water utilizing a straw instead of fumbling with a lid. It doesn't keep the liquid cold enough as some.of the other insulated cups. I wish the design was a little darker, I feel like from a distance it looks like I'm toting around a Styrofoam takeout cup.

The zak! Everyday smiles insulated stainless steel cup is bigger than I expected, the color is really nice and keeps my coffee hot most of the day. The design is great, and it's easy to clean and store.

This tumbler is perfect. It is so pretty and stylish. I like that this keeps my beverages cold for hours. I am able to keep my drink cold all day with ice with this tumbler. I also like that this is easy to hold in my hand.

I am so impressed with this super well-made and totally fashionable travel glass! I absolutely love the mature print and how easily the top twists off and on. I have used it several times at the gym and it has kept my drinks so cool! It is virtually leakproof and has washed well in the dishwasher. I also appreciate that the inside of the cup is marked with an embossed 30oz fill line. I would love to get a matching smaller-sized travel cup in the future!

This cup definitely has a lot of room! The design is really pretty and I like the neutral colors. The bottom of the straw did have some discoloration from the bottom of the cup, which didn't wash off in the dishwasher. But otherwise it seems like a great cup so far!

I have a large collection of cups but am always looking for a new one. I like the size and style of this cup. I switch between ones with straws and then larger ones. This one keeps my drinks cold for a bit which is very important to me, and I don’t like when my cups don’t fit in a cup holder, which this does perfectly.
