I have had the same lousy,standard shaker bottle from GNC for about 4 or 5 years now and it:
- is discolored
- is warped
- works half ass
- clumps like a bitch
- Spill proof (so much that it is the world's first shaker bottle with all rubberized seals to ensure that it is truly 100% spill proof)
- Odor resistant
- Clump free
- BPA free
- Easy to clean/Dishwasher safe
- Great for carrying protein shakes, drink mixes, water flavor enhancers, meal replacements, sports/dietary supplements, or simple just water.
You can use it as a simple water bottle throughout the day!
