I saw them at the Home show, they had the panel off, it is supposed to be a thermal chamber spa, but the spray foam was not consistant, 2x2 frame structure, staples some screws. The dealer had a sign on them that they are an r-47 value of insulation.... and i see they did not meet the CEC standards...... they all showed one of their 8x8 models of a retail of 18,050. during the show you can get it for 9499. i also saw that the same model can be purchased on line for 500.00 dollars less, and retail of 12,499.00,,,, was not impressed..
