The CSR on the phone thoroughly explained why this company was unique- their chemicals and technique are propreitary and completely dry. The service people (2) were honest about the fact that not all stains are soluble with their cleaner (these stains also couldn't be removed by other chemicals that I tried). Overall, I was very satisfied. My only complaint is that the serviceman quoted me the wrong price twice. In the end I paid the correct amount, but I had to do the math myself.
Pros: quick
Cons: price was mis-quoted at time of payment, but was fixed
