We bought an Artesian spa from Casual
Patio, and it leaked after it was installed due to a manufacturing defect. The Artesian spa people were extremely unhelpful, but Ed stepped in to make sure that we got a new one. We haven't had a problem since (it was very clear that the company is not used to dealing with problems since their spas normally don't have any issues).
Even considering the fiasco we experienced, we are extremely happy with the spa and very thankful to Ed for helping us through the entire process.
