[Q]: I got the sea salt and vinegar chips from Kettle.  I am used to the Salt and Vinegar chips in the white bag if I am allowed to say that.  Anyways, my first impression for this is wow at all the chips you get for the price.  I got the 9 0z x 12 bags and wow it is so many for the price.  You can tell they are high quality chips just from the packaging, also.  Well being used to the cheaper chips I wasn't expecting how mellow these things are.  The ones I am used to have a really sour taste to them which I didn't mind but they had tons of flavor.  These chips don't have any sour to them at all, and taste just like them but a lot less strong aftertaste.  If you want to try out Salt and Vinegar chips I suggest you try these out first.  So, for the price and how many you get, these chips are definately worth it.  They are thick and crunchy like the more expensive chips you get at high quality restaurants.  I recommend these, 4 stars.
[A]: Positive


[Q]: This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!
[A]: Negative


[Q]: I drink 10 cups a day of Verona, Italian, or French roast coffee, and wanted to try a lower-acid version. This brand of coffee smells and tastes like vinegar. It is totally unpalatable and you are better off drinking water if the acid in coffee bothers you.
