Strengths and trade-offs

Arno Square 4-in-1

What we like

  • £499 RRP delivers 4-in-1 cheaper than most rivals
  • 2-stage filtration removes chlorine and heavy metals
  • 360° swivel spout handles pot-filling and rinsing
  • Child-safe spring-loaded boiling dispense as standard

Watch out for

  • 98°C ceiling not true 100°C boiling
  • 2.4L tank yields only 7-8 cups before recovery
  • Limited independent reviews outside Arno marketing
  • Newer brand lacks long-term UK reliability track record

Hanstrom Saxan 4-in-1

What we like

  • Distinct square D-shape spout, Hanstrom's current square 4-in-1
  • Touchscreen presets (75/85/90/95°C) for tea, coffee and noodles
  • Genuine 4-in-1 with carbon-and-phosphate filtration (filtered boiling and filtered cold)
  • Usually sells around £399, undercutting most premium 4-in-1s

Watch out for

  • 75 to 98°C steaming hot, not a true 100°C boil
  • Boiler warranty is only 1 year (tap 2 years); 3 years needs a paid extension (~£99)
  • Permanent 'sale' pricing makes the £569 RRP a soft anchor
  • Younger brand with thin published specs (no peak wattage)
