We purchased this as we needed a smaller hot tub, this met that requirement. Very easy to set up and warms up a lot quicker than the last one, not surprising as a lot less water, DOH. The insulating cover is great helps keep the water temperature up.
Two minor gripes hence the 4 star review. The top cover is quite loose and spoils the look of the hot tub.
The other problem is the wi-fi, not strictly the wi-fi, more the app. I can't even register. The app is rubbish, please sort it.
