Ok so last week it was between an new 2013 Jacuzzi J-470 vs the Caldera Niagra. Turns out the Jacuzzi just didn't weather well being stored outside and the cover must have been off for some time as the J1000 controller was badly faded and the tub did not show well at all. I have read many bad reviews on the controller of The D1 and bad reviews on the adjustable headrest breaking down. Not that that's a big deal as there is only 2 of them and the probably last 3 years. I have not found many complaints on the Caldera line. Please leave me any input you may have, I need to pull the trigger asap. Thank you hopefully a new spa owner 😎😎
