I like the product but the pump was very challenging to get to open up. I almost returned it but instead got very aggressive with the top/pump to the point where I felt like I was going to break it when it finally popped up. There was no rhyme or reason to getting it open. The little "open" arrow wasn't any help and didn't have anything to do with the thing finally opening.
