Good construction except for the rubber stopper that goes inside the bottle and then you have to remove it carefully so it doesn't fall in. Mine fell in at some point and I had to grab it with tweezers. The cap is not screw-on so it doesn't close as one would expect. It's basically like a lid that opens with gravity. For home use, though, I think it's good.

Sturdy, no leaks, the small cap (although I was afraid of it at first) does a great job and it's also very beautiful! I got the large bottle, but there's also a 500ml option to make it less heavy.
