Here's how it works. Instead of using mixing accessories like a wire ball or mesh grid, the Tumbler Original uses the centrifugal force generated by a round, no-corners design to break down powder supplements in a mere five seconds of shaking. Shake for another five seconds and you can even enjoy soft fruit in your shake for the ultimate post-workout boost.
You may think having no mixing accessories means a lot of wasted shake. You'd be wrong. Because there are no corners, nothing gets left in the bottle when you've finished with it. This not only means you spend less time cleaning it, but also saves you money as you need less powder in the long-run. No waste also prevents the build-up of the foul smells which develop when undissolved powder lingers in the corners of your typical shaker bottle. It's no wonder we were voted Best Protein Shaker 2019 by Men’s Health and have already received 9 awards this year recognising our Tumbler as the best shaker on the market right now.
