- Ease of installation: Choose extensions that attach securely without modifying the stove, unless the product explicitly requires it.
- Portability: If you travel or camp, lighter, detachable designs can be advantageous.
- Adaptability for multiple models: Some brands offer extensions compatible with several models; evaluate whether one extension covers multiple grills you own.
