I have used this product multiple times.  In fact, I purchased four tubs of the gold and silver luster dust (2 each) five years ago and I am JUST NOW running out!  I use this stuff to gild all sorts of things for Renaissance themed banquets - including gilding an entire roast duck and then, using vodka, painting filigree designs onto it!  The clients thought it was prop food it looked so beautiful.  I can't recommend this stuff enough!

This was not your usual granola bar looking snack.  It was somewhat misshapen making it look more home made.  It was soft which was a plus.  I liked the coconut.  My son, two of my grandchildren and my wife did not like the coconut.  On first glance it seemed yummy, what is not to like about oat, chocolate and coconut?  Obviously in my family the coconut was a negative.  Son liked the taste but not the coconut. Wife didn't like the taste and neither did the 5 & 7 year old grandchildren.  If you are looking for a gluten free non-dairy snack and have no issues with coconut or calories this is a good choice.  The 180 calories put it about 40 calories higher than our favorite granola bar and 80 calories higher than my favorite snack bar.  Uber-sensitive son was dismayed with the lack of protein and he was concerned about the 9grams of fat.  Wrapping it up, for a gluten free snack it is pretty good but if you are not concerned about gluten you probably will want a different snack.  Addendum:the counter woman at my favorite pizza place is on a gluten free diet and loved them.  So that confirms it, as a gluten free snack it got the prize!

We have a tiny little 8 lb maltese, and we got him the mini size bag of these.  Each time we give it to him, he seems to love it, but he had HORRIBLE diarrhea that led to multiple vet visits (it was awful, pretty much the worse diarrhea he's ever had at age 3).  I noticed about 8 hours after he ate the nutrident, the diarrhea started and it had turned blackish green.  Fast forward 2 months, and our dog was nursed back to health and happy...I didn't think that the nutrident was the cause of the diarrhea earlier, I thought it just made it worse so I gave him another one.  Wrong.  About 6-8 hours after, I noticed his normally firm stools were extremely soft and once again, they were blackish green.  I promptly threw the entire bag in the trash.  Terrible product and I will never be buying these again.  As a side note, my little guy tolerates and loves Greenies just fine.  I'll pay the extra few bucks for the Greenies to make sure he isn't food poisoned by these ever again.
