Love This Shaker!
Why didn't I think of this? This shaker delivers on its promises. I read many reviews about the top leaking but I haven't had that problem. (Only have it 10 days though.) I primarily use it to keep my protein drink on one side & ice water on the other so when I'm done working out I can immediately down a COLD protein shake. I gave it 4 stars instead of 5 because of the lid clasps. They don't appear to be extremely durable. Open and close the clasp 50-60 times and it may be time to replace. Overall, a good buy. I highly recommend.
Rating: 4 stars
