Strengths

Reasons to shortlist it

  • Higher-tier starting point
  • Countertop
  • Large Reservoir

These are starter classification signals, not hands-on performance claims. Deeper specification evidence is still being added.

Compromise

Who should look elsewhere?

Starter evidence depth: verify the exact Australian variant, current specifications, price, seller, warranty and retailer availability before purchase.

If that trade-off conflicts with your priorities, compare an alternative instead of forcing a fit.
