I ordered this product and the Urbani white Truffle oil and it arrived broken because they shipped it in a box with nothing inside to protect it. It was just 4 glass bottles thrown into a box and shipped. Also there were no markings on the box to say it was fragile or that there was glass inside.  When I tried to go online and return it I was told the items were not returnable.  So I just bought some expensive, broken, oil.  I will not5 buy from this again and would advise everyone else to do the same.

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.

I was quite excited to try this product, so I bought 4 packs. We opened one, and I tested a half-tablet. No result. My wife tried the other half. Ditto. The next day, we tried a full tablet, letting it completely dissolve over the entire tongue. I found the tablets pretty tasty themselves, while my wife found them too chalky to enjoy. Anyway, again there was no effect with lemons, chili sauce, etc. Our daughter also had no discernible change in her taste of foods.  Happily for me, the company is going to refund me for the other three packages. But I would have preferred that they'd worked. I was looking forward to bringing them out at an upcoming party.
