Love it
I like it. The thing I like is it keeps the water cold for 24 hours, very nice. Also, I use it with me in the pharmacy. Just make sure it is full to keep me hydrated. It is nice-looking and useful.

Bad quality
Got RUST inside after 2 months of occasional usage. How can good quality stainless steel get rusted? I would like to return this item. Would product team kindly contact me

Fantastica e robustissima. Mantiene l'acqua fresca per ore. Consiglio l'acquisto con il tappo con la cannuccia.

Easy to clean

With the ever changing water bottle trends, it can be hard to keep up with what is in and out but the hydroflask was our first and then one we have stuck by - gorgeous colours, lots of sizes and lid options - including straws - it remains our favourite. The only note I'll make is that if you accidentally (completely recognizing that this is my fault) leave the straw up and it falls over, the water spills out QUICK, almost liked knocking over a full glass of water! But if it's down, as it should be, it's leak proof.
