I've seen a lot of negative reviews about this product, but I haven't had any issues with it. It mixes shakes well, it's sturdy, and there's not much of a smell left behind after using it for a while. The only con I would say is it's not insulated so it might get a little cold or hot depending on what you put in it. Other than that, it's exactly what you would expect from a metal shaker.

Very sturdy metal shaker. Better environment and great size. The plastic lid is too weak for the closure and the plastic stop snapped off inside the funnel after a month and perm sealed drinking funnel shut. Strengthen the plastic lid and this would be a great shaker. 

It is really nice, a good alternative to plastic, and it’s not heavy at all. 

So far really pleased. Makes lovely smooth protein drinks. I noticed some reviews stste it is difficult to clean. Well - I just put hot water in the shaker, lid on and shake vigorously. Clean as a whistle!

Shaker is great but lid is very flimsy. Broke after using 10 times. My protein didn’t want to know. 

was worried reading the reviews that it wouldn't last 5 mins. I've had this item a week and it's perfect. No leaks at all. I've ran it through the dishwasher multiple times as well and it's been fine.  I rinse it straight after use just to make sure no smells linger. Only down side is your hands go quite cold when you shake it but works fine.

Just as I’ve read in other reviews (after purchasing) the lid seal closes shut almost too tightly causing the plastic around it to rip when trying to open it. Happened after light home use, always hand washed, exactly 1 month after purchasing. 

I bought two of these, one larger, one smaller. The metal ring around the plastic lid came off within a week, then the closing flap on the lids both tore a couple of months later, after maybe 10 or 15 uses each. A shame because the metal base is great, durable and easy to clean, but now I just have two metal cups without lids, I wouldn't recommend.

Was after a new shaker as if only had the plastic ones and wanted one abit more durable and not huge like some of the others I had. This is a perfect handy size for my replacement meals. Keeps the shake cool also. Easy to clean and mixes the powder perfectly thanks to the blender part sitting in the lid! 😎

This shaker is great, keeps water and shaker really cold and is very useful, also looks great too
