22oz. BPA-Free Plastic Water Bottle Starter Kit with Blue Lid, 3 Flavor Cartridges (1 LifeSip Fruit Punch, 1 FitSip Mixed Berry, 1 GoSip Black Cherry) Zero Calories and No Sugar

This product is great. Excellent flavoring with 0 sugar and other ingredients. The additional filters are affordable, and the adjustable flavor intensity is quality as well. The bottle is big enough to hold ice. Also, the sipping is helpful in avoiding gulping spillage. Easy to carry and excellent for thirsty workers, athletes, or for anyone else. The pricing on this item is good too.

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.

At first I thought this was a scam but I was so surprised on how good it was!! The flavor was so good and if you don’t really like the taste of plain water you need this product.!

Love this Cirkul water bottle. Bought the first one at Walmart and found I increased my water intake substantially. Bought this for my son and he loves it. Works outside and is tired of drinking regular bottled water. Loves the different flavors available and we both drink more water because of this. Bough neoprene sleeves to keep the water cool.

The bottle itself and the concept of changeable flavor cartridges are great. Very convenient, ergonomic, well made from strong materials. The only !! problem is that I've tried over a half dozen different flavors and they are all kind of synthetic. Of course, it can be used for just water, but kind of expensive as a water bottle. Maybe there are better flavors and maybe I'm picky in my taste; I keep trying different flavors. They not bad, but not desirable enough to repeat them.

This product is excellent. You can customize the strength of flavor and the bottle is very sturdy. The flavors are quite tasty. I used #2 to #3 on the flavor dial, plenty of flavor for me and I got almost 7 refill bottles from one cartridge. The bottle is easy to drink from and I’m happy with the 22oz size. Way cheaper than the “hint” water I was drinking and more flavor. I don’t understand the negative reviews, this is a great product. If you want to drink more water this is perfect. If you are looking for a ton of flavor drink soda but then you also get a ton of sugar and other stuff. Love the flavor varieties cirkul offers too. If you want to drink more water with some flavor this is it.

genuinely the concept of this is cool and might get you to drink more water if you severely lack the ability to drink water on it’s own. after owning a cirkul bottle i realized that i enjoy water way more than the flavor that they sell. it doesn’t taste like juice at all if thats what you're expecting. it tastes like those zero sugar drinks and genuinely tastes really artificial. of course thats what you should expect since it’s essentially just trying to get you to drink more water. the bottle itself is made really nice and doesn’t feel like cheap material. the flavors they give with this bottle are not that great but doable if you're just trying to drink more water.

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.
