I have, and I like it. A lot of people (and I do mean a lot) do not like it. I like the protein and potassium.
To me, it has to be toasted, and it has more of a texture of cornbread (very moist and crumbly). I think it might work better as croutons than actual bread slices.
That said, I find myself craving the nutty flavor from time to time. If I couldn't get it from a site where I'm already ordering, I probably wouldn't pay the shipping from the bakery (if it's the same bread we're discussing
). I also wonder a little about the nutritional accuracy, I think the company has been called into question.
All that negativity - I still like it?
If you can find it and don't mind the lighter textures, Heiner's and Healthy Life both make 35 calorie breads, and there are some good 40 calorie ones - though I don't think either mentioned are 'whole' wheat.
Good luck!!
