I purchased this convection cum Microwave Oven last month.I have been using it daily for the last month. It is of 34 liter capacity.It has got three years warranty on Magnetron. The Microwave oven is very well built . It is durable and is stain free.The front panel is touch sensitive and the user interface is very easy to use.The convection mode is very useful for baking, grilling and toasting.The other features like Combination cooking and multi stage cooking are useful as well. It is quite powerful and heats up food quickly.Therefore I consider it a wise choice and recommend this microwave oven to everyone.
