I purchased this as a present but it doesn't come As shown in the picture. It is little white bags with the flavor written on them. Someone receiving it as a gift wouldn't even know what it was unless I explained it to them. Will be returning.

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.

Over the past year my wife has been pushing me (kicking & screaming) into a somewhat more healthy diet with the purpose of helping me lose weight and gain control of my cholesterol. Having me try a number of these fiber bar type things is one of the ways. For the most part I am not a big fan of them but am always on the lookout for one that will appeal to my fat/sugar-loving taste buds. Pamela's Whenever Bars is the latest of a long list of hopefuls. On the plus side; wheat-free, glutton-free, and non-dairy. They include Omega 3 fatty acids and no Trans fats. It's also low in sugar, low in sodium, and low in saturated fats. This is probably a good and quick snack for those with special dietary needs. On the negative site; the taste will be an acquired one, at least for me. It's not a bad taste by any stretch of the imagination but in my opinion it's not one I look forward to either. Maybe it's the lack of sweetness to the bar, or at least not enough sweetness that makes it more of a necessary snack instead of an attractive one. We'll see if it eventually grows on me. Overall, a decent and healthy snack that is not terrible tasting. Could be better but based on other bars I've tried, could be a lot worse.
