[EX Q]: I bought this because I have celiac disease and was really craving some muffins.  I am not a health nut, I just can't eat gluten.  With that said, this is nasty.  It calls for very little sugar, I figure for the health nuts, so I simply added more sugar since it said to sweeten to taste.  Even with extra sugar, it leaves an extremely bitter taste in your mouth.  I would rather pass on muffins than ever taste something like this again.  On a positive note, the muffins do stay together and look like muffins and if you try the product and dislike it, you can mail in the bottom of the box and your purchase price for a refund.
[EX A]: Simply Nasty

[EX Q]: I like the taste, but the store does not always has this.  Some-how it tastes different from the one in the store, much weaker caffeine and aroma...
[EX A]: Strange...

[EX Q]: I find that even with the gain on maximum, the volume is not very loud.  I use it with a Shure SM57 mic and my Macbook (using Audacity).  One must be very close to the mike and speak somewhat loudly.  When I use the Shure mics with a mixer (the "analog" way), there are no volume problems.  It is simple to set up, being almost "plug and play".  You have to choose the input source.
[EX A]:
Poor volume with Shure SM57
