At first, I wasn't sure if spending the money on the shaker was worth it but it definitely was. Using the shaker makes sure that I always get the right portions and makes sure my GSUPPS always tastes good, not to mention the great colors!
Bought a shaker cup along with some gsupps and it was well worth the price.
This is easily my favorite shaker to drink from. There isn’t anything special about it except there’s no wire ball which I hate to clean. There’s a removable mixer blade type thing at the top. I like it because if I put chunks of fruit in there, it blocks it from blocking the mouth piece when drinking. Same with large ice cubes. The small 16oz size is manageable for me since drinking water is a challenge. I get a boost of confidence if I finish one bottle so I go back for more.
