We've had the Wave Pacific for a couple of weeks now and although we have enjoyed it we have found it loses heat rather quickly. The problem with this spa versus the more expensive ones is that it doesn't heat the water whilst the bubbles are running. We found that we had to stop the bubbles every 15 mins to turn the heat on for 15 minutes to try to prevent loosing too much heat. Not ideal, I think it will struggle in the colder months. That said the bubbles are very good and the spa feels well made so I suppose for the money its reasonably good value. You will need to purchase another cover though as the one provided offers no heat insulation.
