Cirkul 40oz. Brink Stainless Steel Tumbler with Handle, All-Day StrawSip™, Double-Wall Insulated

I don't like my new Cirkul 40oz Tumbler, I love it. The flavors are awesome and there is such a good variety of them. Also, I like the enhanced flavors with vitamins and or caffeine, among others. The only thing is I cannot get flavor sipping with the tumbler upright like in the advertisement. I have to tip it up and sip and then I get a flavor "shot" which I wash down with regular upright sips of water. I suppose it works for me just like the plastic bottles. I still like it much better than having to deal with the overly sweet, flavored waters or water flavor packets or drops you get from the store. I also like that you can just drink the water without flavor by turning the flavor dial down to zero. I only want a little bit of flavor like infused water, so I don't mind a lower flavor dial setting, like 3 or 4. You still get quite a bit of flavor at 9. I have filled my 40oz up half with ice and water like, 10 times since I got it, and I am still on the same Honey Crisp LifeSip cartridge. So, I am pretty pleased with how long the cartridges are lasting and how much money I am saving on buying flavored water/diet sodas. Overall, I would recommend this product. As long as Cirkul stays in business, this is a game changer for me as I needed to get away from diet sodas and drink more water. I also got the 42oz regular plastic bottle with a matching chill sleeve directly from Cirkul. I am still waiting for that to arrive, but I am sure I will love it, too. My husband even likes it. So, he is going to be using the free bottle we got from making our first order for drinking with the energy drink sips like InFlow and Fission. If you are looking for a convenient way to increase your water intake and add your customizable flavor, this is product is ideal. EDIT 11/14/2025: I ended up returning this because it became to difficult to get any flavor sipping through the straw. My 42oz. plastic Cirkul bottle works perfectly.

I’ve been using the Cirkul 40oz Ranger Stainless Steel Tumbler for a while now, and it’s made a huge difference in how much water I drink each day. The large size is perfect for staying hydrated without constantly refilling, and the insulation really works—I can leave it on my desk all day and my water stays cold and refreshing for hours. The color I chose looks great too, and the finish has held up well without scratches or fading. One thing I really appreciate about this tumbler is the flexibility of the Cirkul system. Being able to use flavor pods makes drinking water a lot more enjoyable and helps me hit my daily hydration goals. I did run into an issue with a few pods not working properly, but when I reached out to customer service, they were quick, friendly, and very helpful in resolving the problem. That kind of support makes me feel even more confident in the brand. The overall build quality is solid—the stainless steel feels durable, the lid fits securely without leaking, and it’s easy to clean. I’ve used plenty of tumblers in the past, but this one has become my go-to because of its size, design, and how well it keeps drinks cold. If you’re someone who struggles to drink enough water or just wants a stylish, reliable tumbler, this is definitely worth it. I’d recommend it to anyone looking for both function and style.

My husband and son got me this Cirkul water cup for Christmas, and I love it! I really like putting the flavor cartridges in, and it has genuinely helped me drink water more often, which is great since I tend to not drink enough. ​The design is so pretty, and I get a lot of people asking where I got it from! It holds plenty of water and stays cold for many, many hours. It also fits perfectly in the small cup holders and the door pockets of my 2019 Ford Fiesta. ​The variety is amazing—all the different flavor collections they offer are plentiful, and I especially like the B12-infused flavors. It’s a wonderful gift that has made staying hydrated so much easier!

The tumbler itself is a nice size, with the 40-ounce capacity making it great for staying hydrated all day without constant refills. The insulation works well, keeping drinks cold for hours, and the handle makes it comfortable to carry. The StrawSip lid is convenient and spill-resistant. However, like with the flavor pods I reviewed earlier, I still run into the same issue where they often stop dispensing flavor while there is liquid left inside. This makes the system less convenient than I had hoped, especially given the higher cost of the pods. If you already use and enjoy the Cirkul system, this tumbler is a good upgrade in size and insulation, but the pod performance may still be frustrating for some users.

Keep drink cold keeps ice frozen for awhile. But like most cirkul cups if you put the lid on tight you can't taste the flavor. So the lid has to be kinda loose to the flavor will flavor.

This version of the Cirkul is amazing! The smaller ones were always a hassle since I found the motion of lifting it annoying but this solved that instantly and gave me more water! The handle is by far the most convenient feature, the old ones would hang on my fingers and never really work with carrying everything else but the handle, eliminates that completely! Cold water from the fridge I put in it would stay cold for days, and has before, even in places like hot cars overnight, but doesnt freeze if left out in the car overnight in the winter! I use it everyday and have more months now, so of course Ive dropped it and hit it against things, but theres not a scratch on it! Id say Ive damaged more floors with the thing than the water bottle itself! I even took it to a convention and carried around for my trip, not a hint of damage, so those who are worried about it being durable, you're covered! And extremely portable! One more thing I wanna mention, its really hard to get it to leak. If the flavor pod is in securely, cap on or not, this thing won't leak, its actually kind of impressive!

Love it. Use it daily. Handsome.

Love the cup, not a fan of the flavors.

I love the product works well and love that you can change the filter out for whatever flavour you want just wish when ordering on their website they would ship to Canada instead of just Walmart

I love it

I bought this tumbler because I was thrilled at the idea of a Cirkul-compatible cup that didn’t require Olympic-level wrist strength to hydrate. My metal bottle currently weighs approximately the same as a small dumbbell, so hopes were high. Unfortunately… those hopes were quickly humbled. This tumbler is not lighter. At all. If you’re upgrading for wrist relief, please ensure you’ve been keeping up with your forearm workouts. The real letdown, though, is the pod performance with the straw. It works sometimes. Other times, it just decides you don’t deserve flavor today. Nothing quite like sipping confidently and being betrayed by plain water mid-gulp. That said, credit where it’s due, the insulation is fantastic. Ice water stays ice-cold for well over 24 hours, which is genuinely impressive and the main reason this tumbler hasn’t been banished to the back of the cupboard. Overall, I like it… but I don’t love a drinkware item that plays roulette with my flavor intake. Solid insulation, questionable commitment to doing its actual job.

Love it
