Cute but unsure about quality

Cute and handy but rubber lid is too thin and not neatly cut. You can see imperfections in excess rubber and glue in the mouth piece. I am not sure if it is worth its price. Also having doubts if it is really foodgrade. I hope I can share photos. Its looks tiny but it is really 500ml as I tested putting water on it.

Never leave home without

Love this! I brought this with me during my recent trip to Egypt and it was perf! I just stashed it in my bag. I used to bring bottled water anywhere which was not good for the environment, not to mention pricey. Since we have water dispensers at the office, not only is this Kool water bottle eco-friendly but it made me save up from not buying bottled water anymore. Got the color black, it's so elegant! 🙂

Not maintenance friendly :(

I LOVED this foldable bottle. Everyone loves it because it's cute and you can actually fold it. Very convenient, a must for travels and fits everywhere; however, maintenance is pretty hard. The opening/mouth part of the bottle gets dirty and is hard to clean. You still have to use a really small brush to get inside the tiny holes on the drinking part of the bottle which makes it hard to clean :(

I wasn’t able to use it

I purchased 3 of them, hoewever, 2 of those do not have the rubber in the lid that stops the water from leaking. Too bad I can’t bring it to school. Also, the rubber material that is used is not too hard, making it hard to stand on its own.

Perfect for planes, hikes and music festivals

I got this before a trip to the USA because I needed a handy water bottle and I love it! I think other reviewers had high expectations of the product but it’s perfect for my purposes. During plane rides, flight attendants kept commenting that they loved it because it meant fewer times I needed to call them back for a refill and less plastic cups for them to pick up as trash later. I finish my water before going through security and it collapses into a tiny thing which fits my modest travel bag. It was also perfect for the music festival I went to which had free water refilling stations and I could easily keep it come concert time. And since I also did a lot of hikes, it was the ideal size to refill then keep whenever empty. Not cumbersome to lug around and can even hang with a carabiner though I didn’t try as I prefer to keep it in my bag. Obviously it doesn’t keep drinks cold for a long time but for me it’s a reminder to drink constantly! Not for hot drinks ans because of the ridges, I prefer to use water only since it might be tricky to clean if there’s sugars, color, sinkers, etc. Overall, very happy and can’t recommend it enough. Might even give them as Christmas gifts?

I bought this cause i found it cute and i liked that the company is eco-friendly. But the product itself is so-so. Pros: -Good for hot and cold beverages -Doesn’t take up a lot of space Cons: -Cap is not leak proof. My water kept spilling even when the bottle is not full -You can soooo taste the silicone. I’ve washed it so many times and i’ve soaked it as well with hot water, didn’t do anything -When you put flavored drinks, the taste stays for a while -Since it is silicone, whenever placed in the table or whatnot it does fall (so watch out for this)
