I have basic model of Koryo microwave 20L with griller. The fundamental thing is that the user of the oven should be able to see whats cooking in. When I keep my coffee mug inside, I can not see clearly when it starts boiling because of the TINTED glass at front !!!
I have to go close to the oven and try to guess if the coffee boils and spills off the cup. Getting that close to oven can slowly damage the brain due to radiation and make person intellectually weak. Such people can then go on to make products like this one.
I was earlier using LG basic model. It worked well for 5 years. When it failed, the service center could not get Spares and could not give me service. Hence I shifted to another cheaper brand. This one is really CHEAP! Following Text is added to fill up minimum 150 words to post a review.
