If you can't understand what defrosting or fast freezing are, read our glossary of freezer terminology.

Auto fast-freeze: Automatically adjusts a freezer’s temperature to freeze food as quickly as possible.

Chest freezer: A model of freezer in which the door is located on top, like a lid. Chest freezers generally offer more storage space and use energy more efficiently.

Defrost drain system: Provides a path for condensation to escape the freezer via an evaporator tray. This is a feature common to most modern freezers and helps to reduce the build-up of ice.

Defrost technology: Some top of the line freezers use adaptive or usage technology to monitor the usage patterns of your freezer to monitor and adjust the energy consumption based on your daily usage.

Energy Star rating: An energy labelling guide used to regulate minimum efficiency standards. The more stars a freezer receives, the more energy efficient the model is.

Frost-free: Frost-free freezers prevent ice from building up, eliminating the occasional need to defrost. The lack of ice build-up also makes temperatures within the freezer more evenly spread, which improves food quality and the energy efficiency of the appliance.

Multi-flow: A cooling system that circulates cold air more efficiently around the fridge, helping to prevent hotspots.

Side-by-side: A model of fridge/freezer in which the freezer is located beside the fridge compartment. Side-by-side models can come with narrow doors that are useful in areas of limited space.

Thermostat: A device that is used to determine and regulate temperatures in the freezer. The thermostat usually comes in the form of a dial, slide or digital controls.

Upright freezer: A model of freezer in which the door is located on the front, like a traditional fridge. Upright freezers make it easier to access your food.

Ventilation gap / Minimum air clearance: The minimum amount of empty space that must be left at the top, back and sides of the freezer. This allows the hot air that is produced on the outside of the freezer to properly disperse. Check your freezer’s user manual for the recommended ventilation space. Water drain outlet: A drain for manual defrost freezers – assists in removing melted frost. This is achieved with a drain hose and drain outlet, which is usually located at the rear of the freezer.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

HP OfficeJet Pro 8730

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
