Brought the lay-z-spa about 18 months ago. It is easy to put up but not as portable as you might think. Emptying is a bit of a task & takes ages. The elastic on the outer cover snapped on 3 sides after a few months meaning there was nothing to hold the inflatable cover down. It takes at least overnight to reach temperature from cold & as you're not supposed to run the heater for more than 8 hours! Once its reached temperature & you put the blower on, the new version pump then turns the heater off. I've seen on the sites that they say it then loses 1 - 2 degrees an hour but by experience, even on a warm day, its more like 4 degrees in the half hour the blower runs. As the bubbles are made by air through holes in the lining, they can be quite cold if you sit with your back to the wall. Ours is kept in a shed brought just for the spa, with a plastic lined floor but we still empty the pump in winter if the temperature drops as the pump will break down if not. In the year we had this running, we had to have the pump replaced 7 times, sometimes it took them over a month to replace it. The bottem is inflated & comfortable to sit on provided you're not too short. Ours seperated at one og the joins after about 9 months, the repair kit they provide doesn't work on the joins! We can still use it without the bottem being inflated but I have to kneel upright to stay above the water & its not as comfortable. When the warranty runs out, the replacement parts are expensive & we are now trying to decide wether or not to buy a new one & try again! Hope this helps
