Very pleased with this purchase.  Delivery was quick, with good communications and on time. The delivery team placed the spa where I requested and were careful with the delivery.  Set up was easy, and started up with no problems.  I have it connected on 110V power, and it took 2.5 days to get the water temp from 40 degrees to 100 degrees.  However the tub was delivered at the coldest time of the year, so the outside temps were between 18-35 degrees.  I might consider getting an electrician to wire it in to 220V depending on how well it maintains temperatures on 110V.  I really prefer the rot-mold texture to acrylic; the acrylic is too smooth and slippery.  The rotomold has a slightly rough texture but is comfortable and much safer in my opinion.
