Has anybody tried, or have any opinions on, this particular protein powder..?

The link is from the Target website. Since I've been on the hunt for protein powders and protein bars I get these little blurbs popping up all the time.

I currently am using the Think Thin Chocolate Fudge protein bars, got them from Target. Not bad. When those are gone, I already have the Pure Protein Vanilla Protein Powder, shown here:

But I am curious in particular about this 'Grass Fed' one shown from Target. Thanks for anny thoughts ad replies, as always!! :)
