My boys love this bottle. We have had the plastic bottles in the past, this is our first stainless steel bottle. It is excellent quality. Cold drinks stay cold for hours. The bottle doesn’t sweat as much as the plastic bottles, which I love. The top can be closed and opened, by simply turning the top. I like that it can be closed, less mess when it gets knocked over. It isn’t spill proof, but pretty close. You can also take the top apart for cleaning, that way the plunger parts get cleaned as well. It does have a plastic loop on the side. Not a caribeener, just a loop, so you can’t clip it into a bag, that is the only thing I would change about this bottle.
