I have never tried this shake, so I can't comment on the taste. I wanted to give input on the quality of the shake---but I couldn't find the ingredients and nutrition label for the shake listed on the site. Please share this link if you can find it. I also saw that the site sells "cleanses" etc---this is also a concern about this company.
It appears that this is a protein shake. But from your post, I sense that you and your hubby are looking for a meal replacement shake? So the ingredients in the shake should replace a balanced meal not just the protein? I am not sure this is what you want.
A good meal replacement shake are things like: carnation instant breakfast drink, ensure, boost, glucerna, HMR shakes, medifast shakes, etc.
