Review on BlenderBottle C03602 Classic Bottle 28 Ounce by Dustin Miller

I've never had these but they are amazing! The ball as a stirrer is awesome. Produces a nice smooth mix. I use it to mix protein powder, flaxseed milk and water for my morning shakes. It all mixes well after a shake and stays that way throughout the day which is great. Also, all the powder that usually falls to the bottom of the cocktail goes here. I thought the metal ball would be difficult to clean, but it's very easy. I took off a star because the bottle is difficult to close. Sometimes I have to use two hands. Once closed it's completely airtight, but one day it wasn't completely closed and I spilled my smoothie all over the place. I only wish I had bought the standalone version but other than that it's great and so cheap!
