For home use this is a great looking shaker bottle. I have put it in my briefcase for work several times however and it leaks. The top doesn't snap closed securely enough to stay closed, and when the bottle is in a backpack or briefcase and is not standing up perfectly straight, it leaks. I have to wrap the bottle with a paper towel and put it in a ziplock bag when I travel with it to work, and every time when I take the ziplock bag out of my briefcase the paper towel is soaked through from the leaking liquid. I'm still giving this 4 stars because at home it works fine and it's a good looking shaker bottle and most importantly it's BPA-free.
