If you're trawling the end of financial sales for a hot deal on a new oven, don't be misled into buying a dud. An oven is arguably the most important appliance in your kitchen, and often the most expensive, so you'll want to make sure you choose a top scorer.
We test and review wall ovens to help you avoid buyer's remorse (find out more about how we test ovens). If you're making a shopping shortlist, be sure to remove these four low-performing models from Omega, Euromaid, Beko and Bosch.
The Bosch HBF133BS0A oven has catalytic liners, but only on the back wall, which means you'll still need to scrape and scrub the ceiling, walls and floor of the oven to keep it clean, which kind of defeats the purpose of having catalytic liners.
In fact, it's a bit tricky to clean overall: the stainless steel control panel easily shows up fingerprints and the gap between the door and the glass can trap condensation and spills.
It did get excellent scores for low-temperature baking, so it'll turn out lovely meringues, but its high temperature cooking score was less than stellar at 50%, which means pizza without the crispy base. Our experts also scored it poorly for ease of use.
Although this model is the cheapest wall oven we've tested at $599, the Omega OO640 is also one of the lowest scoring.
The cooking performance is fine, but it's the ease of use that really lets it down. The oven controls are confusing, the manual timer isn't accurate, and the gap between the door and the glass can make cleaning a nightmare. Even worse, the oven shelf can tilt under a heavy load and the tray has no stoppers, both of which make it more prone to dangerous accidents.
This oven isn't redeemed by flashy features either – in fact, it has very few oven functions and doesn't even come with a grill rack.
This $1499 Euromaid ETP12XL oven is excellent for grilling and low-temperature baking, but underwhelming for overall performance and ease of use.
Handling heavy oven trays is particularly challenging – the shelf design makes it tricky to remove heavy dishes and the telescopic runners slide out too quickly, increasing the risk of spills.
Catering a dinner party in the $849 Beko BBO60S0MB oven is a recipe for disaster.
There's no temperature grading, so it's difficult to set an accurate temperature, and visibility of food on the top shelf is poor, making it impossible to check on your food without opening the door and letting the heat out.
While its shelves have stoppers, they don't prevent the shelves from being pulled out accidentally, and the shelves have a raised bar at the front and back that can make sliding heavy dishes out difficult. Sounds like ample opportunity for your culinary masterpiece to end up on the kitchen floor.
Hot oven buying tips
According to CHOICE oven tester Fiona Mair, most ovens cook well, but it's the ease of use that separates the average from the outstanding. She recommends checking the controls, shelf design and internal surfaces instore.
"Make sure the controls are clearly labelled and easy to understand. Try pulling the shelves and trays in and out to see if they run smoothly and that there are stoppers to prevent spills," she advises. "Finally, check the visibility through the door and look for awkward gaps in the door or internal surfaces that will be tricky to clean."
