As another reviewer mentioned, these treats are CRUNCHY!. I like them for 2 reasons..my dog can't just "woof them down", she has to chew them, so they last..and I like that the cruchiness may be good for her teeth. The treats are small, but again, are crunchy...I'm glad I found these. She loves them and I like giving them to her.

Thought this might be a nice alternative to use with my favorite coffee, but was sadly disappointed.  It leaked all over - no matter what we tried and the coffee was weak, machine clogged with most attempts and water wouldn't brew thru.  At times the cup even melted a little - leaving a nasty taste in the coffee.  Go with the greener alternative and try the ekobrew - much better results and no waste.

I have been trying the sample sizes of a bunch of different protein shake mixes. I am glad I got the sample size of this one as it is the worst of the lot so far. It tastes super bitter, although, I did not mix fruit with it like the directions say, so perhaps it would be better with fruit. It also irritates my throat for some reason, in fact at first I thought I was having some kind of reaction, but it has subsided since I've started writing this review.  Like everyone else is saying, this 'protein' shake doesn't have much protein. Compared to the other shakes I've been trying, it has the least amount by % weight.  I think that it's unfair for the marketers to put delicious in the label as it is far from delicious.
