Optimum Nutrition Reforce Steel Smartshake, Durable Food-Grade Stainless Steel Protein Shaker Bottle, BPA Free Bottle with Leak-Proof Flip-to-Cap, Easy to Carry Smart Shaker for Protein Shakes, 900 ml

Really happy with this shaker. The stainless steel feels solid and a lot nicer than the usual plastic ones. It keeps drinks cold for a good while and it is easy to clean, which is honestly all I ever want from a shaker. The lid snaps on firmly and I have not had any leaks so far, not to mention it looks slick in the black. Holds about 750ml at max. It looks good, feels durable, and does exactly what I need it to do. Simple win. However it does NOT come with a mixing ball, so you might need to purchase seperately.

The Optimum Nutrition Reforce Steel Smartshake has been a game-changer for my daily workout routine! This shaker is not only incredibly durable thanks to its food-grade stainless steel build, but it also has a sleek and stylish design that stands out from the usual plastic shakers. It feels solid in hand and definitely built to last, with no worries about cracking or wearing out over time. The shaker does an excellent job mixing protein powders smoothly with no clumps, thanks to the well-designed mixing mechanism. Plus, it's super easy to clean, which is always a big plus after a workout. I also appreciate the leak-proof design—I can toss it in my gym bag without worrying about spills or leaks. The size is perfect for holding the right amount of shake, and the insulated steel keeps my drinks at the ideal temperature for longer, whether it's a cold shake or a warm beverage. If you're looking for a high-quality, durable, and stylish protein shaker, the Reforce Steel Smartshake is definitely worth the investment. It’s practical, easy to use, and a cut above the standard plastic options!

Convenient and a good quality shaker cup, decent capacity too. However, does tend to leak if you fill to the maximum level marked inside the cup (which is approx 600 mL), so don't buy if you'd prefer a larger shaker cup.

It’s well made, good size, leak proof seal and keeps the shakes cold

This bottle is so light and easy to carry compared to others! Fits in the car cup holder so great for when I go to the gym. Didn’t want another plastic bottle so this one is perfect when trying to reduce plastics.

Ordered the 900ml version but got the 700ml version. Amazon returns make me contact optimum nutritions but optimum nutritions say I need to contact Amazon. Decided to keep the item as I can’t be bothered with the headache of sending it back. Leaks when not upright and protein mixer system is not very good. Avoid this item and go get yourself a promixx shaker

Would recommend this and would buy the same again. Quality is great and easy to clean. I love the metal inside. Top stars

Seems a good and easy to use product that is straight forward to clean. the internal mesh-lid to help with the mixing seems a bit flimsy, but time and usage will tell. All cleans easy in the dishwasher. I had no issues with reported leakage.

Great!

Omdat het van staal is gemaakt, geeft het nauwelijks geur af. Het is een erg fijn product, ik beveel het aan.

Bonne qualité bouchon qui ferme bien mais je mets 2 étoiles de moins car contenance 700ml et non pas 900ml

I ordered two because I was really interested in a stainless steel protein shaker. However I received one damaged and can not be returned! So be aware of buying this order online, I suggest buying it from your nearest local store. The other one looks fine and works as intended!

Metálico,desmontable en tres partes y fácil de limpiar.
