Wellis Hot Tub - seeking feedback

We close to taking, literally, the plunge and buying a hottub. The model we can afford is the Wellis Jupiter (formally Malaga) 6 seater. Before we spend a considerable sum of money of us, would love to hear from folks that own this model or Wellis hot tubs in general for their experiences of them.

Trying to understand if there is a significant advantage to 1 vs 2 pump hot tub and is the cost of additional electrical costs for power really worth the jump.
