My second Sea Swirl died last week. I wasn't too happy- both stopped working within a month of each other but AC Inc stood by their warrenty and got them back to me within a week. I was told I got mine about the time they got a shipment of bad motors.
One thing though- I wished they would have made sure I didn't have two bad ones when my first one stopped working by having me check the serial number on the second unit. If it would have lasted another two months I would have been SOL.
