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)

Loved at first sight, BUT

I’ve used this before, i loved it and i was all about it. But then as my cold water gets on the normal temperature, i can smell and feel the taste of the silicone/rubbery, its an awful taste and smell. IT SMELLS & TASTE UNSAFE. I gave this a chance, thought it might work again. I rinsed it, soaked it in hot water, cleaned it, basically I’ve tried everything to make it work. Just the past week, i used it one more time to check how it goes. As I’ve arrived from my school and took a sip. The smell and taste is still there... i might just have to say goodbye to this beauty.

Pretty in pink

This foldable bottle can be used both for cold and hot drinks. I just have hard time holding it if I’m drinking hot since this is made up of silicone, ofcourse you have to use hanky to lessen the heat it transfers directly to your hands. It’s travel-friendly due to its foldable characteric, perfect for backpackers. I soooo love the color pink and upon sale, I didn’t hesitate to purchase this one. An addition to my pink collections. ❤️
