I had bought this product last year my dog loved them, but... I subscribe to a couple of Bichon Frise newsgroup and they are saying not to feed these to your dog as they come from China I threw out what I had left for the outside critters in the forest.  I called Dogswell today and they verified that even though they say U.S. on them they are still coming from China.

These Backyard BBQ Kettle Chips were a great deal with the promo code.  It was nice to have a larger size bag.  Some Kettle Chips in the grocery store are only about 5 ounces and we polish them off in one family lunch!  They arrived fresh and were not in crumbles as some other chips from Amazon Grocery have been.  Great flavor and All Natural!

Item appears to be Keurig brand by title & description (big $$$).  However upon receiving it, it is an off brand "My Perfect Kitchen" sold at Bed Bath & Beyond and at HALF the price. I was disappointed in the jading and sent it back. Signed up for BBB email promos and got a 20% off coupon for use in the store so I bought this EXACT item for $20 (reg only $24.99 in store).  I mean EXACT!  Do your homework and save yourself some money.  Oh and the item itself is great...we have the larger Platinum B70 and it does have an issue with the cupboards but I just pulled it forward about 3.5in and it's perfect.  I am fortunate enough to have a lot of counter space and I may move it to an open top area so for us it's all good :)
