I love that this bottle is glass! All the lid parts come apart for easy cleaning.The cap can stay attached so it doesn't get lost. I love the silicone protected bottom.I wish this bottle was bigger. I wish there were exact measurement lines. Also we have had to purchase more than one of these because the glass bottle has broken very easily when being hand washed in our porcelain sink. Even lightly knocking into the side of the sink broke the glass :(Maybe a protective sleeve over the body of the bottle would help?
