OISIZ 40 oz Tumbler with Handle and Straw Lid Stainless Steel Water Bottle Reusable Insulated Vacuum Cup Travel Coffee Mug Cupholder Friendly,Sip or Swig Lid,Leak Proof,BPA Free,Keep Cold for 32 Hours

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 hand Cons: - 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 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!!

My daughter purchased this cup according to my specific requirements, for my Mother's Day Gift. It holds 40 oz. of liquid, Keeps Cold liquids COLD ❄️🥶 for Hours. It came with an opening Cover flap, two straws and my favorite part...a straw cleaner!!! YIPPEE! I enjoy the rubber mouth piece of the End of the straw too! The handle is long enough for me to swing the cup around to use my arm so I can support the cup as I sip my liquid. The screw on lid is very tight and secure as well. My dog knocked the cup over one day, and nothing spilled out. Yea!!! My husband, liked my cup so much that I told my daughter to get one forfor his "Father's Day" gifts!

This is comparable to my more expensive name brand cups. Holds ice for hours. I love the colors!

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.

If you get this at the right time, it's a great deal. That little silicone bite piece is the perfect foil to super long straws. For once, you can tip this big beast over in the car without dumping it everywhere. It's very airtight, unlike some of the others, to the point where you can ear the little air hole whistle as you drink. Built-in silicone pad is great to keep it quiet, too, and it still fits an aftermarket silicone cup to mute it even more. Good color combo to boot. I just with they had more options, this blue & orange is the family fave so far, and we're awaiting some more like it.

100% recommend this tumbler. Will probably buy another color or 2, so nice! Reminds me of the 80s when I would get a new travel mug every summer at a gas station as a kid, great colors. Blue is not my usual color, but this blue color pops & is bright, love it! Stainless steel, nice feel outside. Leakproof! Very easy to clean, light weight, easy grip handle. I have carpal tunnel and this does not hurt my hands. This came with 2 straws and a cleaning brush. High quality.
