OISIZ 40 oz Tumbler with Handle and Straw Lid, Insulated Tumblers Stainless Steel Water Tumblers Bottle for Home Office Car Travel, Keep Cold for 32 Hours, Leak Proof, BPA Free, Sip or Swig Lid

I did a lot of research before choosing a dupe for the brand name version. It’s been a month of using this cup daily and I’m so glad I chose this.Pros:- keeps ice cold for 24 hours- knocked it over a couple of times and no spills- skid resistant bottom means it doesn’t slide around on a table if you move it- unique colors; I left it at the pool and went back for it the next day, the staff knew exactly which cup was mine- the soft silicone straw tip is really pleasant in a tactile way, if you care about that sort of thing- no screws in the handle that could rust or rub against your handCons:- too tall to fit in the cup holders of my Toyota Prius- heavy when full- really huge, looks ridiculous in public tbh. I use it only at home, gym, or in the car. Not at work.I absolutely love it and would 100% buy the same one again.Update: Excellent customer service! The seal broke off the lid when I was opening it one day (my drink temperature had created a pressure vacuum). Contacted the seller to see if they sell spare lids, and they just offered to send me a whole new cup! Highly recommend this cup and seller.

I absolutely love the look, feel and ergonomics of this tumbler. I have yet to put anything hot it, as it is summer, but it keeps my drink ice cold for the entire daylight hours. I can’t say it keeps ice overnight, but the icy temps stay ! I get compliments on it. The colors are so unique and pretty. I purchased the pink one to start and loved it so much, I went back and bought the purple. I have the 30 and 40 oz.It is absolutely leak and spill proof ! I love that I can put my water in with my vitamin powders, seal the top and shake to mix… no leaking at all! It fits perfectly in my car cup holder, as well.I will definitely be buying more for my work day hydration!

I recently purchased this tumbler and it's been an absolute favorite! Its design is not only stylish but incredibly sturdy. I've taken it on several hikes and camping trips, and its cold-retention capability is outstanding, allowing me to enjoy chilled beverages during my outdoor adventures.The material of the tumbler feels high-quality and it's very easy to clean. Even the toughest coffee stains come off effortlessly. The lid is designed to be leak-proof, which is perfect for someone like me who loves outdoor activities and needs a reliable container.Moreover, the insulation performance of this tumbler is impressive. I filled it with iced coffee, and hours later, it was still refreshingly cold! This is a huge plus for those who spend long hours outdoors and appreciate a cold drink.Overall, this tumbler meets my expectations in both functionality and design. I highly recommend it to all my fellow outdoor enthusiasts!

Everyone I work with has multiple super expensive cups but I just can’t spend that kind of money on a freaking cup!! I’m so glad I didn’t because this one is better!! It’s the same size and not only that, the silicone straw is the BOMB!! I got the white/blue color and I am in love! My ice stays in overnight, it’s 99.9 percent leak proof and just a good quality cup for a fraction of the price. I love the fact that I can see through the lid (weird cup phobia on my part) and super sturdy. I bought some straw covers separately (for my daughter’s expensive cup) and when I had MY cup filled to the top, I accidentally knocked the whole cup over and not one drop spilled. Beyond happy with this purchase!!

I threw my Hydroflask and Stanley cups away! The Hydroflask rusted inside😝 and the Stanley cup leaked all the time. I also bought Primula Tumbler from QVC that leaked a lot, the paint on the outside stated peeling the first week. Not this one! I like the big handle, and the sip feature, The price is affordable and my liquids stay cold as well! It’s a little heavy for me to carry but all in all it works for me! Thank you OISIZ! I can afford having 2 at the same time! So happy!Update: I’ve had this tumbler for 4 -6 months and it is still the best but be careful to twist the lid on correctly. If not, it will leak.

I was searching for a large cup that would keep my drink cold for a long time. Another must was that it had to fit in my car cup holder. I bought the OISIZ 40 oz Tumbler. I have used it in three different model cars and it fit all of them. It is a little taller but I don’t find that a problem. I’ve never had a cup that keeps drinks cold like this one. I take it when I play golf and on hot summer days and it really surprises me. I fill it about half full with ice, then fill it up with whatever I’m drinking be it water or thirst quencher and the ice will still be in there till night. I use it every day whether I’m working around the house or just watching tv. I can’t believe there is a better cup.Last week while putting my golf clubs back in the car, I accidently dropped my cup and broke the lid sealing flap. The flap still worked, but wouldn’t latch. I contacted OISIZ and asked how I could get a new lid. I explained about how I broke it and now they are sending me a new lid for free. I couldn’t have asked for better Customer Service.If someone steals my cup, that’s the only way I can see not having it any more, I will buy a new OISIZ 40 oz Tumbler.

The media could not be loaded. This is my second one I have bought. The ice in the video is from two nights ago. And still more than 3/4 full of ice. It’s heavy duty. It’s cute and the rubber bottom keeps is from sliding and clanking around. The straw is two pieces which makes clean up easier. And the cup is actually leak proof. This puts Stanley’s to shame. I adore this cup. I got one for my daughter for school and she has never had an issue with leaking at all. Also this is a HUGE cup. Definitely will buy more and will always recommend these to everyone I know.

I got this cup to encourage myself to drink more water after birth and with breast feeding. It worked. I love the straw and the size. Has held up really well
