Ex Input:
I was introduced to the Blair chips by a friend. I mostly ignore potato chips because I really don't like them. However, these I like the most among all the chips in the Blair line. They are savory and can be eaten rapidly. The hot chips are good because they are so hot, I cannot eat them fast. I am so happy I cannot get them at local stores because I would eat them all the time.

Neat concept. Other contraptions to use your own coffee have prepunched holes and are designed much differently than the K-Cup. This is like a do it yourself K-Cup. However, because this consists of a disposable cup, filter, and a cap and is punched by the brewer, I would not be surprised if this mechanism infringed on Keurig's patents. Oh, and the video review submitted by the other reviewer looks suspiciously like the video on the manufacturers website :)

After looking at the pictures someone put on here showing a crushed box, I had to write a review. I have bought these chips numerous times from Amazon Warehouse Deals and each time they came packaged perfectly. There was a sale at the end of the summer and I received a few cases/boxes for just over $10.00. The chips were fresh and very hard to eat just one bag. I hid them in the garage and only remembered them when I went out there; that way I didn't eat them all. As far as the pictures, if the person contacted Amazon, he made out ok. Amazon is great with handling complaints and this person was given perfect customer service if he called Amazon. Thanks for a great tasting product, good price and quick shipping. I'll buy these again...soon.
