Nice looking bottle, its sleek and the 24oz is the perfect size for me. I was really disappointed with the fact that this doesn't keep my water cold for too long as i've heard it does for other people. The ice melts quickly and turns to room temperature within a few hours (2-3).
The lid that you unscrew to drink from also smells really bad no matter how many times i wash it and it really bothers me. The lid with the straw also doesn't work well, every time i take a sip i get air bubbles and not enough water comes through, which also makes a really loud noise. Although its a nice looking bottle, i don't recommend it.
I mean, it's a great looking bottle. However I don't know if mine isn't vacuum sealed properly (ice tends to melt quickly although the water itself does stay cool inside). Additionally, it makes a weird sound (see video) when you drink from it and it's loud enough that I've avoided drinking from it in class/meetings so as to not be a distraction. I would not recommend this bottle, go with Simple Modern or a more expensive Hydroflask - I have used both of those brands and I've had better success with them.
I was very happy with my first Thermoflask I ordered and thought I would like to have a second one on hand. When I received the second one, the straw lid is different. The part that flips up so you can drink, is now made of hard black plastic. My first Thermoflask has a soft, silicone piece that you can take off and clean and it was the same colour as the bottle. I don't like the hard plastic mouth piece to drink out of. It hits my teeth and It's just not the same. I will be on the hunt for a straw lid that has the soft flip up cap now for my second bottle. You can even see this in the pictures on the Amazon page, there are pictures of bottles with the soft removable mouth piece then the next picture shows it solid black and hard plastic. Super lame.
Update: after looking at the Thermoflask website, they have responded to questions about the straw lid change from the soft mouthpiece to hard plastic. They claim the change was made so it is easier to clean. Thermoflask, I had NO TROUBLE taking the lid apart to clean it. Let's just admit you changed it to sell is an inferior product for the same or higher price so you can make more money. Hint: people will pay for quality. Change the lid back! The hard plastic mouthpiece is terrible when you've had the old soft silicone one before.
It holds water I guess... and the straw top is a nice addition BUT the paint comes off very easily. It rubbed against a smooth metal pole on the bus and the paint chipped. From my experience, my water didn't stay cold for very long. Maybe for 3-4 hours but it's nothing compared to what nicer bottles manage. I've had bottles keep water cold for nearly 24hrs without a problem so this is a huge disappointment.
I bought this water bottle and loved it but when I went to go use the lid that came with a straw it didnt work which was upsetting. Idk If i can return the lid for a new one and keep the water bottle? I love this water bottle besides the lid issue.
