The Optimum Nutrition Reforce Steel Smartshake has been a game-changer for my daily workout routine!

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.

Excellent shaker and bottle for water. Good quality, solid, not leaking, easy to use and clean. I use it every day for months and still all good. Brilliant value for money

The Optimum Nutrition Protein Shaker is a solid choice for anyone in need of a reliable and affordable shaker. It feels sturdy and well-made, so I expect it will withstand regular use. I particularly appreciate how easy it is to clean – a quick wash by hand and it's ready to go again. It's a decent size, more than enough for my regular protein shakes and the little steel ball helps to break up and lumps making it easy to use. While the plain black design is sleek, it can be a bit tricky to see the liquid level inside. However, this is a minor inconvenience compared to its overall functionality. I've had no issues with leaks, even when giving it a vigorous shake, and the flip cap keeps everything secure, I do hold onto it tho, just in case! If you're looking for a good value, no-frills shaker that does the job, the this a good option.

Excellent Love it its perfek Cheers ears

Only been a week, couldn't be without it. Easy to use. Shaker mixes really well, easy to clean and great quality for the value. Highly recommended.

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.

It's ok... There's a bit of liquid that leaks even when it's tightly shut which is a bit annoying. Other than that it's a regular shaker that I'm not sure if it's better than other shakers on the market. The price being way higher is a bit weird though since the quality doesn't exactly seem much different to a normal sports water container.

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.

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

The bottle is cheap plastic

Unfortunately, the description of the cup I purchased stated it was made of stainless steel, but the cup that arrived is made of plastic.

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!
