Im really enjoying me new spa!  I literally plugged it in and put water in it and it was ready to go after 2 days.  The only real set up to it was installing the cover clips so the cover could be latched down.  The inner material is a little rough, but not that big of a deal.  I filled the water up a little higher because i like to have my shoulders covered (im 5'7"), as a result, i cant see the waterfall, but im ok with that. Ive owned a regular hot tub in the past and the jets are just as powerful as the "real kind."  For the price, i feel like this was a great purchase and im super happy with it!!
