Contigo Shake & Go Fit 28oz Shaker Bottle Carolina Blue Leak Proof Cap Smoothie

I adore the round bottom for good mixing and easy cleaning, the mixing ball, the wide opening for easy cleaning, the large drink opening for chugging, And the carrying hoop. My only complaint with the old model was the bottle material did absorb ingredients over time. I hesitated buying the new model because I was unsure about the new screw on spout, and the new material since contigo didn't specify what the material is. Still i gave it a shot since contigo has proven to be pretty smart. It turns out the screw on spout is better than the old snap design, and so far the anti-stain material is staying cleaner than 2 competitive products I'm also trying, which are using the tritan material. So for now, after a few weeks, 5 stars

I have been purchasing these shaker bottles fo years. My family members seem to walk off with them when they visit because they are so awesome. So happy they are dish washer safe. The ball is durable and helps break up clumpy protein powder. Overall, these are a staple in my home because of their durability.
