Replaced a Vegas. Three could sit in this Singapore comfortably. Cannot see how more is possible unless you are a bit squashed. Water level has to be just 10cm above the inlet filter or once you are in the water almost overflows and does when bubbles are on if filled to even min level. Wifi control is very handy. Seems to be well made and sturdy. Middle bubbles nice on legs. Does feel an upgrade to the Vegas. Takes up less space for a slight loss of interior. Heats up quickly.
