We've had our Vanguard for 4 months now. We use it almost every night. The kids enjoy it as much as we do and it's been a great family investment. My utility bill has not gone up very much, maybe $30 a month more. The moto massage is great as are the other jets. The lights that change color automatically is also a cool feature. We got the pearl interior and it looks great at night with the color lights. The only problem we've had is the interior control panel failed after only 3 months and our dealer can't seem to get a new one for us. The dealer told me it's a common problem. There is no way that is should have failed after only 3 months considering we paid close to $9,000 for the new tub!
