    No pill divider

    Like the thermal Blender Bottle better I purchased also. The pill storage on the ProStak doesn't have a pill divider and the lid on the lower powder container is hard to grip to get open.

    Got it for my husband and his gym workouts. He’s always having to take a second container for his protein mix. This is a perfect idea! So glad they came up with this bottle!

    Best shaker for those on the go

    Love this shaker when I need a water bottle but need to drink pre-workout and protein later in the day. Supplements fit easily in the two attachable jars and are ready to go when I need them.
