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

There are many flavors to choose from, which makes it almost impossible to get tired of any given flavor. I have the 40 oz, which makes it easier to remember that a minimum of 1 refill is required. It is a little expensive to start, however if you start on about 4 you can make a flavor cartridge last for 2-4 days. I wish this cup had the ability to stay cold longer. I have to refill the Ice in the AM, prior to work, yet it is completely melted by the end of the day. The cup fits nicely in the cup holder of the car, making it easy to travel and continue to meet your water goals. The handle also makes it easy to take sips while driving.

As a circular drinker this cup is amazing. I love how it keeps my water cold and it give me a cup that fits into my cup holder. The handle makes it easier to carry. And the width of the cup makes it VERY easy to clean. Now the top does leak if it tips over, but overall no complaints.

I ordered this cup because my daughter and I were too excited to try Cirkul and didn’t want to wait until our order was delivered to start trying these guys out. The cup was very nicely priced and I purchased flavors from Walmart. I will say there may be some kind of bug in the design as sometimes the flavor doesn’t come through, only water even if the flavoring is set to 7,8,9 etc. however for me, I like that because I really do love drinking water wether plain or lightly flavored or heavily flavored. It’s got my kiddo drinking SO MUCH water. Which is great because she never ever drinks enough. I can’t wait for her 22oz bottle to arrive so she can take it with her to school and etc. this is an awesome addition to my plenty plenty of cups.

This while a great cup and I like having the flavor strawsip, the lid is an absolute nightmare to get off! So many times I fight with being able to get the lid to unscrew, even when I didn't tighten it that tight. It makes refilling it with water very difficult. f you have difficult gripping items or with hand strength, you definitely do not want to buy this cup, you'll never get the lid off. I feel like I wasted money on this because it is so difficult for me to utilize with having so much trouble getting the lid off.

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.
