Strengths and trade-offs
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)
Quooker Fusion Round
What we like
- True 100°C delivery reported in T3's review
- Vacuum-insulated tank consumes ~10W idle (~£24/year)
- 7+ premium finishes including patinated brass and rose copper
- Quooker UK holds high Trustpilot rating across 12,000+ reviews
Watch out for
- £1,250 RRP roughly twice the Qettle equivalent
- 2-year warranty on tap and tank (SWAP is a paid out-of-warranty tank replacement)
- Filter/sparkling requires separate CUBE module (extra spend)
- Trustpilot reports £455+ repair cost for out-of-warranty units
