Still totally worth it. We love the dome. I have gotten used to eating Ramen noodles and Hamburger Helper instead of steak & lobster. Now the heater is having issues. Looks like we need a new control board. It has two settings..on and off with code R-13 (I think). :/ We can't control the temp anymore so it stays off when not in use or we end up with Virginia's largest hot tub. It has been warmer here so it does not take long to heat back up. That will definitely cut down on the CCF. My husband is waiting for a good 2 days with no rain to open it up and see what is going on. We can order a board online and replace as needed.
