"⭐⭐⭐⭐⭐ Really happy with this shaker! It mixes my protein powder really well without leaving any lumps, and it’s very easy to use and clean. The quality feels great, and the lid seals properly with no leaks. Definitely a good purchase, and I’d happily recommend it to anyone looking for a reliable shaker."
"No more worries about cleaning those annoying metal balls No leaks AND It doesn’t stink for the rest of it’s life of the previous protein powder …Amazing"
"Lock system - great, Conical shape is terrible - so easy to tilt over, and rubber on the bottom makes it only worse! Diameter of the neck - cannot wash it properly because hand doesn’t fit in. Finally, the inner shape of the lid has many small cavities where protein collects and without toothpick is impossible to wash out. Thrown it away and continue using the previous one."
"It’s tough choosing between this and Opti’s metal shaker, as the latter keeps things wonderfully chilled for ages. That said, this new shaker does a great job of getting your shakes silky smooth with little effort. Would definitely recommend!"
"Sincèrement je ne m'attendais à ce que le shaker soit aussi efficace. La tenue en main est géniale, et l'opti-lock aide à empêcher les fuites de liquide. Je suis très satisfait"
"I am so in love with it. High quality materials and comfort!"
"Best ever design of a shaker in my opinion. The static plastic removable agitator is a game changer. Easy to pop out to clean more thoroughly, easy to pop back in. I’ve used this a few times now for cold things: shakes, coffee drinks, milkshakes."
"It's so dark I can't read the measure when filling. And because it's so tall it doesnt stay in my bag side pocket. Also while the locking lid is innovative, it also means it's a pain because i can't just throw the lid on and turn like I can with the original Promix bottles. The mouth piece is a great improvement as is the look and indent for holding."
"It still smells even after washing."
"very good quality"
