We use the second month. Really like! But I already want more stones! Got pros: Very compact and not expensive thing! It's nice to cook and warm up food not standing at the stove after work, but sitting at the TV, on the raclette bowl, drinking your favorite juice) With its cons: A little grease splashes, but we found a way out. We lay the oilcloth.
I thought it would be useful to include some photos to help readers visualize my experience.
