32 oz plastic starter set with navy lid, 2 blueberry and kiwi berry flavor cartridges

I was a little sceptical about buying it after it became so viral. I was unsure of the hype, but since being pregnant water hasn’t been satisfying enough and this is ideal!!

Granddaughter loved this

Taste: The taste was amazing and I loved how you can change how much of flavour you get

Kids love them

Hard to get the different flavours when it's run out. High quality bottle though

What a waste of money. Sorry but this is a gimmick and not nice tasting at all.

Great idea, love mine, but you can't get the refills easily if you are in britain

Well made bottle comes with two cartridges just wish it was easier to get more cartridges in the UK.

El producto llego cuando el vendedor dijo solo que también llego algo rayado como si a la hora de empacar lo rayaron.

I won’t go into too much detail, just my experience and recommendations. Cirkul really works for encouraging non-water drinkers to stay hydrated. I’m living proof. Some may think, “I can just buy a water enhancer packet or bottle, I don’t need this gimmick.” And while that may be true, the difference for me is the ease and functionality. With Cirkul, I can adjust the flavor instantly instead of juggling two bottles or being stuck finishing and refilling one. I just fill my bottle with cold water, and the moment I get “tired” of plain water, a quick dial turn adds flavor. When I’m ready for plain refreshing water again, another turn brings it back. Simple! “But” here’s what you need to know. Getting the advertised 120 oz of flavor comes with a learning curve. The advertised amount of refills or usage is not misleading, but there are details to consider: • Choose the right bottle size. Don’t buy a massive one if you won’t finish it in due time. The flavor cartridge drains when left sitting, especially if the bottle stays in the fridge or you don’t remember to set the dial to off. Smaller bottles encourage “fill, use, refill.” Larger ones only make sense if you know you’ll empty them. Point being don’t get into the habit of leaving it in a fridge to sit. Fill and use. • Turn the dial off after sipping. Don’t leave it sitting on a number, this wastes flavor. • Sip, don’t chug. If you vacuum or hard-chug with flavor on, you’ll drain the cartridge faster. Your level 6 will be like getting a level 8 (You’ll get a huge flavor burst and then your cartridge will just finish faster) • Avoid freezing the bottle. Freezing messes with the cartridge and there’ll be less space for actual water to flavor in the bottle. If you prefer cold water like I do, consider putting icy cold water in or adding ice. • It’s common sense math. Yes, you can get 120 oz at the DEFAULT setting of 3. But for many of us non-water drinkers, that flavor is insufficient. My sweet spot is 5-6 which gives me ~64oz per cartridge, maybe a bit more. I want to put into perspective that this is a bit more flavor than a capri sun roarin waters drink. This is all variable but I will say, don’t expect six 20 oz refills (120oz) at anything stronger than a 3 setting. Usage is cumulative and not additive, at any setting higher than 3, you’ll get less and less flavor per cartridge. Hope I’ve covered it all. As others have said, most of the flavors are great. My son enjoys them as well (make sure to buy the non caffeine cart for kids, they are marked to easily recognize the type. If it’s a lightning strike, not for kids). My wife also loves it as well. She’s not big on drinks or juices but does want a splash of flavor now and again and now she’s found the perfect thing. I fully recommend this bottle.

El termo excelente, los sabores muy feos

Si cambia el sabor pero el sabor es demasiado artificial, y casi sin diferencia entre ellos

I like Cirkul as a product, but the problem with this large bottle is that it isn't insulated. If you live in a warm climate, I'd recommend you consider an insulated tumbler instead. Cirkul in general is great for increasing your healthy water consumption if you are used to soda, energy drinks, etc. because it flavors the water automatically. I like the huge variety of flavors and the ability to customize how strong the flavor is. However, the flavor cartridges can be expensive, especially if you drink a lot and like strong flavor.
