Appearance:
The workmanship is not perfect but pretty good. The turrets are something too easily, and does not help at all to use.
The inside of the furnace is painted. Send additional but without unnecessary. Scratches are inevitable, of course, here. But it's just a stove / oven and not a Ferrari.
The grate and the plate, however, are other reviews neither pointed nor sharp edges.
Power:
The performance is within the scope of the device. Who wonders awaits you, should keep in mind that the unit is connected to a normal 230V outlet, and does not come to the power.
The plates are hot and fast heat well. The furnace is unlike other reviews also quickly warm (in 1-2 min. Pre-heated) and additionally to keep isolated to the heat better.
Conclusion:
For the price the device is good. Who can find a 28l cooker and 2 plates meet is satisfied here. Of course it does not come close to a pro-Gastro-device, but this takes it indeed not, but for normal use, it is quite suitable.
