This product works just as advertised!! Guitar center told me the only way to connect my mic to my computer was either an expensive converter box or a usb mic. A-HOLES haha. I love this little gizmo and would definitely recommend it to a friend!!

Ex Input:
Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.

Ex Output:

The Ener-G English muffins that I received from Amazon were not of the same quality when I buy them directly from the distributor in Seattle.  They crumbled and had dense places that were not really edible.  Also, there were only 4 in the pack instead of 6. I had to cancel my recurring order.
