Spa was delivered as promised, set up was  easy and the instruction booklet was even laminated for use around water !!! The motor runs quietly and the jets are powerful ... or can bet set in a relaxing mode.  An automatic timer can be set to turn the spa motor on or off ... or to run at a specified times during the day/night, determined by the spa owner.   Love, love, love this hot tub ... Thank you Wayfair !!!
