Very easy setup. Had it going in less than 20 minutes.  Filled it up and was able to use in 24 hours.  It seems to hold the temp well. Very happy with this the bubble jets provide a nice massage on your back and shoulders.  The included headrests are nice too. I recommend buying the drink shelf to hold your water bottle or beer.  The only drawback i’ve seen so far is the inflatable thermal spa cover that goes under the main cover seems to lose air and I need to fill it weekly.  I’m going to test it for a leak.
