We are excited about our new spa and use it every day.  After plugging it in, we waited 2 full days for it to come up to 101 degrees. It hasn't had a temperature issue since then.  The spa is of great quality and comes with a heavy duty cover. The design of both the spa and the cover is very nice, the jets work really well, and the colored lights in the water are a fun extra. We are a family of four around and above 6 feet tall and there is plenty of room for us all.
