Great bottle - just nothing else to say. Does what it says on the tin and comes with blender ball

Very reasonably priced for a solid, tight fitting, product. The wire ball mixes impact whey and creatine in only a few shakes and easy to wash without that stale milk smell clinging to it.

Does exactly what it says on the tin. No leaks and mixes my impact whey perfectly. 

I received this free and the quality is great. I use it for every single protein shake after my workouts and it is holding up well. The metal shaker is such a great help and prevents lumps of protein powder

Does the job, but I found out that you need to be careful where your finger is when holding the bottle near the lid, as when you close it, there's an extended bit of plastic, which can pinch your skin if it's near it.

Really like the shaker, really easy to use and gets rid of all the lumps that would normally have if trying another shaker.

The shaker is really nice, it doesn't open on its own and doesn't leak, so you can keep it safely in your bag. I give three stars because even if it's allowed to wash it into the dishwasher, mine has burst and I had to throw it away. Before this episode, I always washed it by hand.

Love this bottle, blends your shakes to perfection with the spring ball, no clumps at all

still shakes. does what a shaker should - shake good like, tight seal, mixes stuff. I sure loves me a gud shaker...

The shaker is fantastic - the coil seems to do the job of mixing much better than any other I have found. Unfortunately, the top does not seal completely so there is always a minor leak.
