Protein Powder comparison

Has anyone tried the Kaizen protein powder from Costco? 

It is on sale at Costco this week and I would like to know how it compares with others.  Is it good?  Should I avoid it?

What brand do you use?

I buy the chocolate one I like it, I use to buy isoflex chocolate before but after trying kaizen chocolate I haven't tried any others.. It mixes really well in a shaker. I use use almond or soya milk to me it taste like chocolate milk.. For the price can't go wrong.. If u do buy it keep the receipt and don't like it u can get refund. 

I just bought it as well.  I went to Costco to get premier protein shakes and price went up again.  Almost $10 case in a year. So I saw that protien powder on sale so thought I'd try it. First day with water, was ok.  Today I tried with milk.  Not bad. Will probably take me few days get use to it.
