Best pump I’ve tried

I have tried many different pump products , this is easy to scoop out of the container. Most clump together and have an odd texture. There is non of that in this product! The taste Is nice and doesn’t have that grainy taste most pumps have. It mixes will with no effort, and product does what it’s supposed to do. Will buy again
