This is the second "Tug-a-Jug" food puzzle I've purchased for my wire fox terrier. The first lasted about five months until she chewed through the rope. But this toy kept my dog more occupied than any other food puzzle I've tried, so I decided to purchase a second one. My plan was to put this one away as soon as my dog was done with her food so she wouldn't "play" with it and chew through the rope. So in other words, I blame my dog's destructive terrier prowess on the demise of the first toy rather than the manufacturer.  But after just one week of use for the second toy, the bottom part where the end seals onto the main container literally cracked and shattered into many pieces when I was sealing the toy.  My dog may chew through ropes but she's not that rough with toys, and I was using normal strength to twist the end piece on, so I'm pretty sure this one was a dud. But after that, I'm totally done with this company. The shards that came off in my hand were tiny and sharp enough that if just one shard had broken off without my notice and go mixed in with my dog's food, she probably would have ingested it and had internal bleeding.

Ex Output:
Negative

I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.

Ex Output:
Positive

I wish I had come to the Amazon site before purchasing this product at my local Wegman's. The 'Product Of China' was printed so small it was easy to overlook. I am a little shocked that Wegman's (a local chain store known for quality) was selling these 'treats' in a big display. The half open package is going in the trash and unopened bag is going back to Wegman's for a refund and a piece of my mind.

Negative
