I can heat it only once empty and cleaned according to how it is described in the instructions. The device can smell when heated first, what it has done. Unfortunately, the smell did not dissipate even after prolonged use. I've only after (together) almost 4 hours of operation barely smell.
The sandwich maker is only suitable for thin sandwiches. 2 pieces of toast, 1 slice of sausage, 1 slice of cheese is grad still ok and because you have to press already fixed, so that the lock can engage. In addition, tomato, cucumber oa is indeed to press yet, but is really very difficult and I think that would also be the hinges too much burden on duration. These make namely a bit cheap / thin impression.
The preparation time of the sandwiches is ok with about 4 minutes ... then they are crispy and the inside also pretty hot.
The plates must not be grease, it sticks nothing. If cheese runs out, you can easily remove the back of the plates. Unfortunately, the cheese runs in the groove and the locking of the plates, where it is difficult to remove. The plates I had in the dishwasher (which lt. Instructions yes is possible) and it has not harmed them.
Wafers not succeed with this device, unfortunately. Since the heat / power is too low. I made waffles simultaneously with this 3 in 1 device and a waffle iron. At the time (about 10 minutes) where I made 3 heart-shaped waffles with the waffle maker, was completed at the 3 in 1 device not even the first. The waffles were still light outside and inside they were still doughy.
Barbecue I have tested with thin small sausages and have to say even here he is not convincing. Although it works, but it is quicker in the pan.
Thus, I have to say that this is not really worth 3 in 1 device. Not bad, it is only as a sandwich maker and as a single unit is preferable, because then there is usually no lock next to the plates in which collects the cheese.
I prefer to stay with my individual devices, a nice table grill with on / off switch, a waffle iron with thermostat and soon probably still a reasonable sandwich maker.
Addendum 18:11:12: I continue using the device as a sandwich maker and now (after only 2 months of occasional use!) Already allows the power to. He tans very one-sided, one-half is golden brown and crispy, while the other is still a bit soft. The device is no longer using. Thus, I correct the evaluation of original 2 stars to 1 star.
