I received my Spa during mid March but waited until mid April to set it up until the weather became a bit  warmer.  Start-up and Spa Maintenance  is simple and straight forward.  This a quality, well built product  It's easy to see that the manufacturer paid much attention to detail and workmanship. I am very pleased with my Spa, honestly, it is very similar to an upscale model Spa I considered buying locally for more than twice the price.   I am no stranger to Spa ownership, for the last 8 years I owned a portable hot tub that packs up into two boxes at the end of the season.  The Spa in the Box functioned adequately, but Lifesmart Spa is the "real deal" for about twice the price of the Spa in the box. 
In summary,  I am very happy that I upgraded to the Lifesmart Rock Solid Simplicity  Spa.
