Sport Stainless

Absolutely love the stainless version. Obviously loud with ice, but quality is excellent. The locking lid is extremely useful. Mastery item might have been my favorite choice though.....fun, exciting and got a very cool, vintage plastic version of the original blender bottle I originally had for multiple years. This one had a pastel purple lid, with florescent green bottle. Super cool!!

Very good

A major upgrade as now my first and last sip are ice cold for my workouts. The only thing I don’t love is that the loop behind the lid isn’t adjustable as it is with the regular shaker bottles

I run a lawn maintenance company, use a cup every day. For the most part I am very satisfied with 1 exception. I filled the bottle with my dew, started mowing a fairly rough lawn when the cup built up to much pressure and the top blew off. Still haven't found the cover
