Horrible, they never honored my Groupon.. They never showed up as scheduled and once I did get through to find out what happened they were not willing to work with me to re-schedule a time that worked for me. Do not use these people, they used one excuse after another to explain their "issues" especially about not showing up.
A business that puts themselves before the customer is not a business I choose to deal with. I finally filed a complaint with Groupon and got my Groupon account credited.
