Super easy to start up.  Remember the trick is to open the jets when filling (this is the purging)  and then close when heating.   It took me a couple of weeks to get the chemicals aligned but now only test once a week.  Do recommend to stop by a pool/spa shop and have your tap water tested.  This gives you a print out of what you need. We have had the spa for about 5 weeks using it most every night.  This spa gives us the enjoyment and relaxation with out the spending thousands.
