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.

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

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.

Great shaker doesn’t leak and good quality

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

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.

Very good value, works well for water or shakes, no leaks.

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.

Great!

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
