What we like

  • Pull-out hose rinses sinks plus full 100°C boiling
  • Same vacuum-insulated tank delivers true boiling water
  • Magnetic dock returns hose neatly after use
  • Boiling flow auto-locks when hose is detached from base

Watch out for

  • £1,295 RRP matches Fusion despite extra moving parts
  • Trustpilot owners report hose fraying within several years
  • Hose replacement is a paid call-out, not 5-min DIY
  • Requires 500mm depth + 200mm width clear undersink space
