I would not use them again. I feel the business practice is questionable. There prices were extremly higher than comparable business. I had a hard time getting an itemized price for the purchase. The owner wanted to provide this only after credit card purchase. The equipment provided was broken, most we're very old with frayed wires. It seemed as though there were no set prices and no matter what items were chosen he made sure there would be an out of pocket expense of no less than 300.00. The amount spent on groupon was 300.00 and he wanted to collect that much more upon redemption. The reason I made the purchase was because I thought it was a great deal. Please consider my comments .
