No, not mine, but my hot tub is 1yr old today. At least it was delivered a year ago today. It sat for a day until my BIL/electrician hooked it up. Either way, it's been a year of spatopia!
The novelty has worn off for my kids, but the wife and I still use it regularly about 5x per week. Although since school ended for the kids a couple weeks ago, I've changed my usage habits. When we first got it, I always used it at night. Found that after getting home from working out at night it was very relaxing and helped me sleep. However, without the kids getting ready for school, I have extra time in the morning and found that using the hot tub is a great way to start the day. Especially lately with temps in the 50's or 60's overnight. Sitting in the tub listening to the birds and watching the sunrise is just as relaxing as star-gazing at night.
No problems with the tub, although I did have to have the cover replaced, which the dealer did no questions asked, after a handle ripped. Hopefully it will continue to be problem-fee because starting tomorrow my dealer will begin to charge a fee for service calls.
