Other reviewers are right that it is hard to see the measurement labels without holding the bottle in the sun. I recommend just grabbing a permanent marker and tracing over the measurement marks. Seems fairly sturdy like it isnt going to break on you, and its a good size. For those who are saying that the hole at the top is too small, it looks like there is a faint line up there that indicates that you are supposed to cut it. Thats what I did when I used it to dye my hair and I didnt have any problems. Anyway, Id say this is nothing spectacular, but it does get the job done.
