I bought this product in the hopes that it would help me cut out sodas and drink more water. I am absolutely 100% in love with this product and Ann very glad I purchased it. I would definitely recommend it to others, in fact I have already got two friends to purchase one as well!

Solidly built, could likely beat someone with this then sip out of it - IF IT WORKED. Drinking from this takes a stupid amount of effort, andall the online recommendations to 'suck harder' are pathetic at best. The system to let air BACK in so you're not fighting a reverse vacuum is the worst implementation I've seen. ZERO understanding of the variance of human biology here. You need a pump to get water out. That said, once you burst a lung getting water out, the flavor is decent and as said the build is solid. Maybe I'll grab my Dremel and cut a hole in the refill cap to allow free air passage when drinking. Coulda, shoulda, woulda. Don't waste your money, get a WORKING water bottle and fill it with flavored water. Just sad and useless.

Love this product. When Nestle Splash priced me out of their flavored water i switched to Cirkul. Its cheaper %26 just as good. You set how strong you want your flavor. I prefer my flavor light, I only turn mine to 2 out of 9. A cartridge lasts me 3 days %26 I drink water all day every day. I fill my bottle about 8/9 times a day. Less plastic waste in the garbage. i have a large stainless %26 a smaller one. Highly recommend.

First time trying it because it was on sale and the regular price was to high but I'm glad I finally got it so far I love it it's only been a couple days I'm glad I can adjust the flavor but wish I didn't have to drink it like it's a straw I love that they make flavors with caffeine to keep me going throughout the day or sweet tea on hot summer day I'm hoping they make more flavors like for fall pumpkin spice or mint tea and a way to be able to drink it like a regular water bottle opening would be awesome. But my honest opinion is it's great I always have to be told drink more water so now I do lol.

My new obsession! L o L .this item is fun and hygienic and makes me want to drink water. No leaks. I wish there was more flavors that were not sweet.

Ordered for autistic grandson finding that this can be expensive but the overall system I love for my husband, and other family and friends

My grandson Love his new cup I gave it to him for his birthday. He was very excited to have what he asked for. I surprise him on his birthday and every child that was there was telling their mom to buy it for them.

The top leaks every time you take a sip. It’s always a mess. Very disappointing. The refills are not cheap neither is the start up kit. I expected better quality.

Love it. Im definitely drinking more water. Love the variety of flavors.

It's easier to handle than the larger bottle.
