What to know before buying
- Compatibility is not established for every oven named in the broad brand claim. Compare the 33 mm thread and 40 mm height with your existing cover and check your precise appliance model. Take appropriate safety precautions during appliance repairs. Gas-appliance repairs should only be made by a Gas Safe Registered engineer.
- The customer feedback reports positive experiences with fit and installation, but also includes concerns about durability, with some reports of breakage after only two days. Glass replacement parts may not suit buyers prioritising proven long-term durability.
