... you're car or at the gym I do not recommend this product
unless you want a protein explosion in you're car or at the gym I do not recommend this product. After securing the top clasp I began to shake my bottle only to find that the clasp opened therefore spewing protein all over my car. I think the concept behind the cup is great but the stability and durability was not well thought of. The blender bottle clasps click when closed and it takes a little muscle to open it back up, but that lets me know it's secure, whereas on this cup I didn't know when it was open or closed completely and the clasp would fall off regularly.
