Is the Hisense PureFlex RQ5P640SYSD worth it?
Yes — the best big fridge freezer for most homes.
It holds 640 litres across four doors, makes ice and pours cold water from a tank you fill yourself, so there's no plumbing to install. One freezer drawer can switch to fridge space. In a two-week lab test it cost about £35 a year to run, very low for its size. The water isn't filtered, and the fridge ran about a degree warmer than set, so turn it down one notch.
Good to know
- It's 74 cm deep, so it sticks out past a standard worktop.
- The fridge runs slightly warmer than the setting; set it a degree lower.
- You refill the 5-litre water tank by hand.
- 640 litres, four doors
- Ice and water with no plumbing

How we reached this verdict
Trusted Reviews names it its best fridge freezer overall: in two weeks of testing temperatures were stable and it cost about £35 a year to run, 5p per litre of space. Which? also lab-tested it. We found no verified owner reviews at the shops we read, so there is no owner score yet.
We compared independent expert reviews with the manufacturer's specifications, then checked it's sold at a major retailer where you live. We don't test products ourselves.
