Used 5-6 times so far for beef steaks, skewers, burgers (not too thick), chicken, sausages, and various vegetables (mushrooms, peppers, onions, sliced eggplants, etc.) with excellent results. For some, it may seem a bit slow (depending on how one is used to cooking), but for me, it's just fine.
It really cleans up easily with paper towels (2-3 times to get everything off and not burn every time on the plate).
I chose it (at 52 Euros) after seeing almost everything else available, due to the 2500W, for its dimensions (it could accommodate 2-3 cm wider, the 46 cm length I consider the minimum for 4 people), because it seemed - and proved to be - a sturdy construction, for the design of the handles, and mainly for the shape of the heating element that is visible in the photo: I believe the second inner curve is very important for high and even temperature (other models may have it too, but they don't show it in the images)
