I've tried other shaker cups as well as just stirring up a protein shake in a normal cup. This is by far the best way to easily mix a protein shake. My wife and I load up the supplements and can take it with us to the gym easily. We just add water when we're done working out and shake for 20 seconds. It always rinses clean easily. I just ordered 3 more so we will have plenty to go around.
The lid on this shaker snaps on and is not water tight. What good is a shaker that when you shake it, leaks from the cap? Yeah the blender fins are pretty cool but i'm not sure what they add, plus if the lid drips what good are they...Save your money and get a traditional shaker.
This is my favorite shaker cup for protein powder. Simply add your liquid to the appropriate ridge, a scoop of powder, a few shakes and voila! - the powder is mixed in thoroughly without incorporating too much air (no nasty bubbles). You can even comfortably drink straight from the cup (easy clean up). Simple and effective, it makes my morning great! And at $3 from netrition.com, how can I resist buying more?
Mixed feelings about this, really. On one hand, it mixes perfectly, never any clumping. On the other hand, it really isn't designed well to actually be drank from. Liquid accumulated on the inside rim and runs on to your shirt, pants, etc. No big deal, but annoying nevertheless.
So my first protein shake was made fine. I held the top on because of the other reviews saying it came off. Tonight in my hotel I now have a filmy chocolate concoction all over my mirror.
If you shake it you literally have to hold the top on, this thing is a piece of crap really. It's not even worth 10 cents considering the top just pops up if you shake it. Netrition needs to stop selling this thing. I'm either throwing it out or giving it to a friend as a gag and am going to laugh at him when the chocolate protein shake comes spewing out all over the place.
Editor's note: Make sure top is pushed on hard until it clicks, then always hold your fingers over the top and begin shaking slowly.
why would you buy a shaker that leaks? Can't they figure out how to make these? Its like buying a car that does not run. This thing leaked when shook on the first attempt. Its junk, if you dont mind a little liquid leaking out buy it. But if you want it leak free dont get it.
