This is my third classic electric shaker bottle. My first two experiences lasted for about a year, but both failed. The first time it was a bit rough and the butt gap was cracked. The second man made a slit in the spout.
And, you see, these two problems have been solved in the second-generation classic voltrx protein shaker bottle. Be sure to like to listen to feedback and make improvements to the company.
Anyway, the 28-ounce classic voltrx protein shaker bottle has always been my favorite size, function, and price. It fits the center console of my car perfectly and is absolutely leak-proof. The new design, round bottom and protective edges seem to perfectly prevent future catastrophic failures.
