We ordered Aquarest spa. We filled it, turned it on & in 2 days it reached temp! I removed cover, went to change, my daughter & grandson & i got in & it was only warm! Jets were turned on & it continued to cool off. Seller said it doesnt heat with jets on but its a friction heater! Aqua spa will not take it back unless I pay $800 shipping! For a spa that doesnt work. I purchased by description but it doesnt work as described. Beware & dont purchase this tub if I need a HOT tub! This one is only warm! User's recommendation: Do not purchase. Aquarest does not allow returns for spas that don’t work right!
