Has anyone tried Costco's Betty Lou's Low Glycemic Whey Protein Shake Powder?

I tried a single packet from vitamin shoppe.it had a different taste to me than most others I have tried but I could drink it easy. I tried the chocolate but haven't tried the vanilla one yet.

Thanks. I ended up buying it. I'll post when I taste it if anyone else is interested.
