I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.

I bought two bags of these, thinking it was the same product that I used to buy in different packaging (light blue, with a see-through dog shape against a grass green background). Unfortunately, it was completely not the same thing! These treats were actually like jerky-- tough and brittle. I give my dog soft treats because he doesn't chew the damn things, and he choked on these horrible things; I had to toss them out.  Note that the "Zuke's Jerky Naturals" with the other packaging (http://www.amazon.com/Zukes-Jerky-Naturals-Beef/dp/B00008DFPY) have always been moist and soft, and I've never had a problem with those. I suspect that this batch was not new packaging, as I had thought, but very old packaging; these may be the same treats I usually feed my dog, just having sat on a shelf for years. In any case, these were COMPLETELY different treats, and not safe to feed my dog.

These chips are awesome. The light airy texture makes them a pleasant snack. I am dieting and thesse fit in reall nice. Gives me that salty, crunchy yummy taste that keeps my points low for the day. I love them. I have recommended them to all my diet buddies and they love them. I haven't tried all the flavors yet, only those in the variety pack but trust me I will be tracking them all down and hopefully find my favorite. That may be difficult they are all so good!!!
