Built Solid
I just started using this today so it’s early on.  The cup is built well.  It feels heavier than my Blender Bottle.<br /><br />I can’t speak to durability yet, but of it fails, I will update my review.  I have concerns with the longevity of the locking flaps but they state they are well built and will hold up.  If not, they will take care of it.<br /><br />The opening tabs lock back so you don’t have to hold them as you drink.  Well done.<br /><br />The grid seems to mix the product well versus the metal ball.  I little bit more to clean as it can clump on the grid but that happens with the metal ball as well.<br /><br />So far, I’m really digging this one.  💯
