Mine arrived with the zip-lock feature of the bag damaged so I could not safely store the contents in this bag. Instead I put it into a container I had from another brand of powder that came with a big plastic bottle (holds over a gallon). That way I didn't have to worry about bugs getting into it and it's easy to open and close.
I probably would not buy this product again simply because a large quantity cost over 50 bucks and could not be stored safely in the bag provided. I think the powder itself is probably a good product. Tastes good and works good. It's just the container that is not manufactured very well and could not be relied upon to safely store the product. It takes me over a month to use a big bag of this stuff, so the ability to safely store and maintain the quality of the contents is very important.
I doubt that providing a bottle-type of secure container would add much to the cost (shipping plus material). From my experience almost all manufacturers of protein powders ship their product in the large plastic bottles. I think that is very good and there is never a problem keeping the contents safe and fresh.
On the plus side, the customer service representative was very helpful, responded quickly and was very nice and courteous. I did not return the product because I had an empty bottle available in which to store the powder.

Love this protein shake. Have been using it for years. Low calorie and low carb with a great taste. Never chalky!

Best tasting whey protein. Blends very well and adds creaminess to my smoothies.

Highly recommended. Not bloating, no weird fillers.

love that this product is still staying by its principals and giving us both taste and quality!
