Pros: I purchased this as replacement sound for a computer with an integrated sound card that failed. Not expecting much more than to be able to hear error messages and listen to informational videos this little bugger has out preformed and is able to provide me with a semi-rich sound and when paired with a decent set of speakers does very well. I was also desperately short on PCI slots so the USB interface was just right for my needs. Very easy to setup and install ... plug into USB port in a Windows 7 or better OS and let the magic happen.

Cons: none as of yet, but again I'm not expecting life altering sound. Just functional is what I wanted and this exceeded that level of expectation.

Pros: Telephone system works. It does give me a phone number that is 100% based off of my internet connection. Was very easy to register and setup.

Cons: Isn't free after you pay for the equipment. They have you register a credit/ debit card during registration. For 2 months in a row I've had small (approx. $4) charges each month entitled Ooma. Also I live about 30 Miles North of Green Bay, WI and was unable to port my current telephone number. My only option was to select a Green Bay telephone number. This is an inconvenience that I was not expecting. (I really should have done my homework and looked into the cities that they do have local coverage for) All-in-all I would be happy to sell this unit to somebody for $100 that lives in a city that has a local Ooma number.

Overall Review: My phone service is about $25 a month right now after taxes and spending the money on this experiment was equivalent to about 7 months of my phone bill, and I'm no farther ahead. I was looking for a good way to cut my bills and this really didn't do it for me.
