I see people saying it leaks or something along those lines. That is not my experience. I have used it every day for a few months now and it is perfect. I love the metal, it never holds a scent, never retains any powder, always easy to clean, never a problem with the seal or the lid itself. I am so happy to eliminate the plastic shakers that would deform, or smell if I ever forgot to rinse it out immediately. This is by far one of my happiest purchases. 

Great for work as kept smashing bottles as they fell! Thought I would try this and within 2 uses the cap which flips open the bottle completely ripped making the bottle unusable. Very disappointed this occured, never had this happen on the other protein bottles in the past.

The seal in the lid doesn’t seem to link up with the seal on the bottle. When shaken vigorously, the shake begins to come out of the bottle.  It is a very difficult bottle to do up and leaks if laid down. 

The shaker is nice to use and has a premium feel, however after use to the product, the cap with covers the area you drink from has split deeming the shaker useless. Very disappointing having only used the shaker sparingly in the 6 months I have had it

This worked very nicely as a shaker and I liked the stainless steel construction. However after a few months the lid broke. Sometimes the plastic lid was difficult to open and eventually the force required snapped the plastic.

Didn’t expect much from it considering it’s just a shaker, but it is leaps and bounds better than the plastic shakers, leaves no horrid smell when simply rinsed out with water and mixes all protein and carbs very well.

By far and away the best shaker I’ve ever owned. Mixes perfect everytime. 

Well, I read the reviews before buying it, and thought the cap MIGHT break and nothing MIGHT shake in it... However, its a great shaker! Cap is strong and tight, even though I believe you can break it as there is stopping point when open( Thus not really great to drink when driving :( ) Impact Protein Whey from here shakes great as well! A lot of shakes and no bits :) Feels strong and nice in hand :)

I’ve thrown away all my old plastic shakers and replaced them with this metal shaker. Its amazing. No more horrid smell like the plastic one. No more lumps, and keeps the shake nice and cold. Would 100% recommend. 

Looks good, keeps your shake cold and seems to not smell unlike plastic shakers. Unfortunately it does not mix protein powder very well, no matter how hard I shake it I still get lumps. Also should be noted i'm using MyProteins Impact whey with the shaker.
