It is indeed stainless and durable. It cleans easily and in the dishwasher. I recommend it for children.

I was not impressed with this purchase! I bought 2 for 15 euros. One was never waterproof, it leaked. The other one was difficult to open (even for an adult) until you found the trick to open it. One out of the two, on the first serious fall, broke the cover from the straw and is now useless

I bought 3 for my children. They didn't last even a year. From the falls, constant dents were formed on the metal container, resulting in the bottom being completely round and the bottle not standing at all. I believe it doesn't have the required durability and it is a purchase for short-term use (taking into account the ages for which it is intended). Otherwise, it doesn't leave any odors, it is a relatively good quality construction.

After 10 days of use, my little one accidentally dropped it and broke the lid, so now it can no longer close... We can't take it anywhere except at home...

It does not leak and does not smell if the water stays in it all day. The only downside is that it is somewhat difficult to open. My little one who goes to kindergarten struggles to open it.
