We purchased a Golden Designs Inc. three person sauna from Costco back in 2013, about 3.5 years ago. It was easy to assemble (and move once), and it worked great. It did exactly what it said, and exactly what we wanted. And even when the power supply broke from a power surge, we were able to get a plug and play replacement very quickly and fix it very easily. The customer service team was as great as the sauna itself. I could not be more pleased, and will definitely consider buying another sauna from them when the time comes.
