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
Quooker Classic Fusion Square
What we like
- Period styling in a squared spout for Shaker and classic kitchens
- Patinated brass develops a genuine patina rather than a printed lacquer
- Same PRO3 tank and 100°C boil as the rest of the Fusion range
Watch out for
- 3-in-1 only: no filtered or chilled water without the CUBE upgrade
- Patinated brass needs an occasional beeswax wipe
- Fewer finishes than the standard Fusion (no gold, gunmetal or black)
